Answer:
5x²-3x-14
Step-by-step explanation:
(3x-6)(2x+3)+(2-x)(2+x) = (6x²+9x-12x-18)+(2²-x²)
= 6x²+9x-12x-18+4-x²
= 6x²-x²+9x-12x-18+4
= 5x²-3x-14
Answer:
(x - 2)(5x + 7)
Step-by-step explanation:
(3x - 6)(2x + 3) + (2 - x)(2 + x) ← expand factors using FOIL
= 6x² - 3x - 18 + 4 - x² ← collect like terms
= 5x² - 3x - 14
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × - 14 = - 70 and sum = - 3
The factors are - 10 and + 7
Use these factors to split the x- term
5x² - 10x + 7x - 14 ( factor the first/second and third/fourth terms
= 5x(x - 2) + 7(x - 2) ← factor out (x - 2) from each term
= (x - 2)(5x + 7) ← in factored form

Answer:
f(-2) = -5
Step-by-step explanation:
Actually, the function g(x) is irrelevant here. We need only evaluate the function f(x) = 3x + 1 at x = -2:
f(-2) = 3(-2) + 1 = -6 + 1 = -5
f(-2) = -5

Calculate the measure of the missing angle of the
quadrilateral pictured below:
E 110°
F 65°
D87°
G?
The missing angle measures
Answers
Step-by-step explanation:
The angles of rectangle add up to 360°
So the missing angle + 65 + 110 + 87 = 360
The missing angle + 262 = 360
The missing angle = 98°
please give me a brainliest answer
Step-by-step explanation:
? + 65°+ 110°+87° = 360°
? + 262° = 360°
? + 262 -262° = 360° - 262°
? = 98°
A garage sells cars.
It offers a discount of 20% off the normal price for cash.
Dave pays £5200 cash for a car.
Calculate the normal price of the car.
Answers
Answer:
6,500
Step-by-step explanation:
Discount = 20%
Therefore the cost price is 100 - 20 = 80%
so,
£5,200 = 80%
To find the 100% ( the cost of the car before the discount), invert the fraction.
100/80 x 5200/1 = 6,500

Solve for x. Help Help Help Help Help, I tried dividing 17/2 which gave me 8.5 but it’s wrong
Answers
Answer:
x = 15.9
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + x^2 = 17^2
36+ x^2 = 289
x^2 = 289-36
x^2 =253
Take the square root of each side
sqrt(x^2) = sqrt( 253)
x = 15.90597
Rounding to the nearest tenth
x = 15.9

What's the slope of (6, 5) and (3, 7.5) ?
Answers
Answer:
The slope of (6, 5) and (3, 7.5) is 5/-6.
As a decimal: (-0.83333333333...)
Step-by-step explanation:
Formula for slope:
[tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]
('m' means slope.)
[tex](x^1,y^1) =[/tex] coordinates of the first coordinate point
[tex](x^2,y^2)=[/tex] coordinates of the second coordinate point.
--------------------------
Coordinates:
[tex](6,5)(3,7.5)[/tex]
-------------------------
Now, I will simply plug the numbers into the formula.
[tex]m=\frac{7.5-5}{3-6} =\frac{2.5}{-3} =5/-6[/tex]
As a decimal: (-0.83333333333...)
The slope of the given points is 0.833
Slope, m, is given by the formula
[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
From the question
[tex]x_{1} = 6[/tex]
[tex]y_{1} = 5[/tex]
[tex]x_{2}=3[/tex]
[tex]y_{2}=7.5[/tex]
Putting the above parameters into the formula
[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
We get
[tex]m =\frac{7.5-5}{3-6}[/tex]
∴ [tex]m= \frac{2.5}{-3}[/tex]
[tex]m = 0.833[/tex]
Hence, the slope of the given points is 0.833

Answers
Answer:
x=55*
y=125*
Step-by-step explanation:
In parallel lines, opposite angles are equal to each other so x=55.
In lines, adjacent (side by side) angles always add up to 180 so,
x+y=180
55+y=180
y=180-55
y=125

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
let's solve for " w "
[tex]vw {}^{2} + y = x[/tex][tex]vw {}^{2} = x - y[/tex][tex] {w}^{2} = \dfrac{x - y}{v} [/tex][tex]w = \sqrt{ \dfrac{x - y}{v} } [/tex]Answer:
w = √( x - y ) / v
Step-by-step explanation:
in this situation, we are actually asked to make w the subject of the formula
this !means that we should make w be equal to every other variable meaning;
w = y + x
note that this is just an example
so, let us get started
we have;
vw² + y = x
first of all we have to move the y to the right hand side
it is more like collecting like terms so that at the end of the day we only end up with w on that side
vw² = x - y
now, we have to remove the ²
we will do that by square rooting both sides
√( vw )² = √( x - y )
the square root will remove the square because they are opposites of each other.
it is more like a multiplication sign canceling a division sign or when we bring a subtraction sign to the other side of the equation and it turns to an addition sign.
in our case, it is like bringing the square to the other side of the equation and it turns to a square root sign
so,
vw = √( x- y )
we ate almost done.
it is now time to remove the v by dividing through by v
this means that we remove the multiplication sign bonding the v and w through division just like the square root removing the square
vw / v = √( x - y ) / v
w = √( x - y ) / v
therefore , our answer is
w = √( x - y ) / v
