3x(x+30°) i really need help asap

Answers

Answer 1

A13x2+390x here is the answer

Answer 2

Answer:

x=15

Step-by-step explanation:

Simplifying

x + 30 = 3x

Reorder the terms:

30 + x = 3x

Solving

30 + x = 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

30 + x + -3x = 3x + -3x

Combine like terms: x + -3x = -2x

30 + -2x = 3x + -3x

Combine like terms: 3x + -3x = 0

30 + -2x = 0

Add '-30' to each side of the equation.

30 + -30 + -2x = 0 + -30

Combine like terms: 30 + -30 = 0

0 + -2x = 0 + -30

-2x = 0 + -30

Combine like terms: 0 + -30 = -30

-2x = -30

Divide each side by '-2'.

x = 15

Simplifying

x = 15

Since, Points P, Q, and R are collinear and Point Q is between P and R.

[tex] \therefore \: PR = PQ + QR \\ 13n - 10 = 4n + 3 + 6n + 8 \\ 13n - 10 = 10n + 11 \\ 13n - 10n = 11 + 10 \\ 3n = 21 \\ n = \frac{21}{3} \\ n = 7 \\ \\ PQ =4n + 3 = 4 \times 7 + 3 = 31 \\ QR = 6n + 8 = 6 \times 7 + 8 = 50 \\ PR = 13n - 10 = 13 \times 7 - 10 = 81[/tex]

sold to gain
should it be
rs 444?​

Answers

Answer:

Hence, the watcg must be bought at rupees 4888

Step-by-step explanation:

Let the desired selling price of the watch be x

Cost Price of the watch = 4444

We know that if Cost Price < Selling Price,

Selling Price - Cost Price = gain

When we substitute we get,

x-4444=444

Write a formula for the area of the regular polygon.

Answer:

The area of any regular polygon is given by the formula: Area = (a x p)/2, where a is the length of the apothem and p is the perimeter of the polygon.

Step-by-step explanation:

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients. The formula when solved for h will be equal to A/4b.

What is a polynomial?

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication, and non-negative exponentiation of variables involved.

A.)

For the given octagon, if its diagonals are made then it will be divided into 8 triangles, such that each triangle will be equal to the other.

Now, if the area of a single triangle is calculated then the area of the triangle will be,

Area of triangle = (1/2) × b × h

Further, since there are 8 triangles, therefore, the area of the octagon can be written as,

Area of octagon = Area of triangle × 8

                           = (1/2) × b × h × 8

                           = 4bh

Hence, the area of the octagon is 4bh.

B.)

The formula can be solved for h as shown below,

Area of octagon = 4bh

A = 4bh

Divide both the sides by 4b, therefore, we can write,

A/4b = 4bh/4h

h = A/4b

Hence, the formula when solved for h will be equal to A/4b.

The definition of parallel lines requires the undefined terms line and plane, while the definition of perpendicular lines requires the undefined terms of line and point. What characteristics of these geometric figures create the different requirements?

Answers

Answer:

Parallel lines requires the terms line and plane because line and plane that are parallel cannot cross each other therefore they will never make a point of intersection. The characteristics of that parallel lines consists of lines and planes. Perpendicular lines requires the terms line and point because whenever two lines intersect, it creates a point and whenever two planes intersect, it creates a line. The characteristics of that perpendicular lines are points and lines.

The characteristics of the geometric figures that create the different requirements are;

Parallel lines are lines on the same plane and that are equidistant from each otherPerpendicular lines are lines that form a 90 degree angle at the point of their intersection.

Reasons:

The characteristics of parallel lines are;

The shortest distance between the lines that are parallel is the same at all points along the lines.The lines are on the same plane.As the plane is extended indefinitely, the lines do not intersect.

The characteristics of perpendicular lines are;

Perpendicular lines are lines that intersect at a point.

Where two lines are perpendicular, the slope of one line is the negative reciprocal of the other, such that the product of the slopes of two lines that are perpendicular is -1.

The angle formed at the intersection of perpendicular lines is 90°.

An horizontal and a vertical line on the same plane are perpendicular to each other.

Therefore, the characteristics of the geometric figures that create the different requirements are;

Parallel lines are lines on the same plane.Perpendicular lines are lines that form a 90 degree angle at the point of their intersection.

Hi there!

Let's solve your equation step-by-step.

[tex]6(m+2)+6m=-5(-7m-7)[/tex]

Step 1: Simplify both sides of the equation.

[tex]6(m+2)+6m=-5(-7m-7)[/tex]

[tex](6)^{(m)} + (6)(2)+6m= (-5)(-7m)+(-5)(-7)[/tex] (Distribute)

[tex]6m+12+6m=35m+35[/tex]

[tex](6m + 6m)+(12)=35m + 35[/tex] (Combine Like Terms)

[tex]12m + 12 = 35m + 35[/tex]

[tex]12m + 12 = 35m + 35[/tex]

Step 2: Subtract 35m from both sides.

[tex]12m + 12 - 35m = 35m + 35 - 35m[/tex]

[tex]-23m + 12 = 35[/tex]

Step 3: Subtract 12 from both sides.

[tex]-23m + 12 - 12= 35 - 12[/tex]

[tex]-23m = 23[/tex]

Step 4: Divide both sides by -23.

[tex]\frac{-23m}{-23} = \frac{23}{-23}[/tex]

Find the slope of the line parallel to the given line.
y= 2/5x+2

Answers

The slope of the line is negative four tenths

Slope:

[tex]\sf{\dfrac{2}{5}}[/tex]

Explanation:

Parallel lines have the same slope, so the slope of y = 2/5x + 2 will be the same as the slope of the line which is parallel to it.

The equation is written in slope-intercept form, aka y = mx + b, where m is the slope and b is the y-intercept.

In slope intercept, the slope is always the number that comes before x.

For this equation, the number in front of x is 2/5.

So, I come to the conclusion that the slope of the line parallel to y = 2/5x + 2 is 2/5.

What would be the cost for 5 of the gift cards? $80 $90 $100 $110

Answers

Answer:

the answer is 100$ on endgunuity

Step-by-step explanation:

The cost for 5 of the gift cards is $100. Therefore, option C is the correct answer.

What is the equation of a line?

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Given that, blue diamonds appear at points (1, 20), (2, 40), (3, 60), (4, 80).

Now, we will find m and c using the points (1,20) and (2,40)

Let x be the number of gifts cards and y is total cost (in $).

The slope, m = (40-20)/(2-1)

m = 20

Equation of straight line is given as,

y = mx + c

Put the value of m,

So, y = 20x + c

Substitute with the point (1,20) in y=20x+c, we get

20 = 20×1 + c

20 = 20 + c

c = 0

The equation of the line, y = 20x

To find the cost for 5 of the gift cards substitute with x = 5

y = 20×5 = 100

So, the cost for 5 of the gift cards = $100

Therefore, option C is the correct answer.

What is the square root of 10p^3

Answers

Answer:

Factor 10 into its prime factors

          10 = 2 • 5  

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

In our case however, all the factors are only raised to the first power and this means that the square root can not be simplified

At the end of this step the partly simplified SQRT looks like this:

        sqrt (10p3)  

STEP

2

:

Simplify the Variable part of the SQRT

Rules for simplifing variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

     (3.1) sqrt(x8)=x4

    (3.2) sqrt(x-6)=x-3

   (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples:

     (4.1) sqrt(x5)=x2•sqrt(x)

    (4.2) sqrt(x-7)=x-3•sqrt(x-1)

Applying these rules to our case we find out that

     SQRT(p3) = p • SQRT(p)  

Combine both simplifications

        sqrt (10p3) =

       p • sqrt(10p)  

Simplified Root :
