Answer:

I am not sure if you want it to be a simplified answer but the simplified answer is 10 x - 6

Answer:

x = 59

Step-by-step explanation:

since the quadrilateral add up to 360 degrees,

X + X + (2x + 3 ) + (2x + 3) would equal 360 degrees

x + x + (2x + 3) + (2x + 3) = 360

6x + 6 = 360, addtion

6x = 354, subtraction

x = 59, division

Answer:

31.4 in

Step-by-step explanation:

This is a tricky question,

if you observe the shape carefully, you will notice that if you mirror (flip outward) each curve surface of each quardrant, what you will end up with is a complete circle with a radius of 5 inches.

Hence the combined length of all the curved surfaces is simply the circumference of the circle, given by:

Circumference = 2πr

= 2 x 3.14 x 5

= 31.4 in

Answer:

D and E.

Step-by-step explanation:

Each angle is a different length and no sides can be the same length. If two angles are the same the triangle is considered an isosceles triangle. If all sides are the same it is an equilateral triangle.

Answer:1.15

Step-by-step explanation:

2/5 =.40

.75+.40=1.15

Answer:

1.05

Step-by-step explanation:

2/5 is equal to .4%.

We can then also interpret the equation as "What number is 1.4% more than .75?".

We need to only multiply 1.4 x .75, to which we will get 1.05.

Answer:

160

Answer:

We know the volume formula of rectangular prism is:

Volume = Length × Width × Height

We are given:

Volume = 1428 in³

Height = 6 in

Length = 17 in

Width = p

Apply the formula!

1428 = 6 × 17 × p

1428 = 102p

Divide by 102 on either side to isolate p

p = 14  

The width is 14 inches

Step-by-step explanation:

Answer:

11 and 51

Step-by-step explanation:

1 technically isn't a prime since a prime can only be divided by two things (itself and 1) and 1 can only be divided by 1.

21 can be divided by 1, 3, 7, and 21 so it is not prime.

Answer:

23ft

Step-by-step explanation:

Area of the rectangle = LW

L is the length

W is the width

Given

Area = 414ft²

If the length of this garden is 5 feet longer than its width, then;

L = W+5

Substitute into the formula

414 = (W+5)W

414 = W²+5W

W²+5W-414 = 0

W = -5±√5²-4(-414)/2

W = -5±√25+1656/2

W = -5±√1681/2

W = -5+41/2

W = 36/2

W = 18ft

Since L = W+5

L = 18+5

L = 23ft

Hence the length of the rectangle is 23ft

Answer: C: It did not rain on 3 days; it did rain on 4 days

The solution to the equation of graph is it did not rain on 3 days ; it did rain on 3 days

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the equation of graph be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The graph is rising on 0 to 1 , 2 to 4 and 5 to 6

The graph is a straight line from 1 to 2 , 4 to 5 and 6 to 7

So , the graph is rising represents the rain was there for 3 days

And , when the graph is a straight line , the rainfall was absent

Hence , the graph represents it did not rain on 3 days ; it did rain on 3 days

Explanation:

The curve is going downhill as you move from left to right, and as you move from x = -3 to x = -1.

The interval notation of (-3,-1) means -3 < x < -1.

Since the curve is going downhill on this region, this means the function is decreasing on this interval.

Yes, the function is decreasing over the interval (-3,-1).

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given interval is (-3, -1).

The curve is going downhill as you move from left to right, and as you move from x = -3 to x = -1.

Answer:

x = -3.5

Step-by-step explanation:

Divide both sides by 1 to get rid of the 1

x - 2 = -5.5

Add 2 on both sides

x = -3.5

Answer:

x = -3.5

Step-by-step explanation:

1(x - 2) = -5.5

x - 2 = -5.5:  Distributive property

x = -3.5: Subtraction property

Answer:

The answer is...... NO

Step-by-step explanation:

Step 1: Plug in your values in the x and y cordinates.

2(5) + 8 > 18

Step 2: Solve

Then you multiply 2 and 5 and get 10.

SO then your equation should look like this:

10 + 8 > 18

The answer to the question is no because in order for this to work it would need to be the greater than or equal to sign, which looks like this ≥.
