8. A student is cutting a square out of a piece of poster board. The area of the poster board can be represented as (4x² + 14x - 8) in?. The area of the square can be represented as
(x2 + 8x + 16) in?. Write an expression to represent the area of the poster board left after the student cuts out the
square. (Lesson 14.3)
I

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
