Answer:

(gof)(-8) = 210

Step-by-step explanation:

(gof) = (-x + 8)² - 3(-x + 8) = 2

= x² - 16x + 64 + 3x - 24 + 2

= x² - 13x + 42

(gof)(-8) = (-8)² - 13(-8) + 42

= 64 + 104 + 42

= 210

Which expression can be used to determine the length of segment AB? On a coordinate plane, triangle A B C has points (4, 3), (ne

JulijaS [17]

Answer:

StartRoot 2 squared + 6 squared EndRoot

Step-by-step explanation:

we have

A(4,3) and B(-2,1)

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the given values

$AB=\sqrt{(1-3)^{2}+(-2-4)^{2}}$

$AB=\sqrt{(-2)^{2}+(-6)^{2}}$

$AB=\sqrt{40}\ units$

therefore

StartRoot 2 squared + 6 squared EndRoot

xeze [42]

Answer:

13x-2

Step-by-step explanation:

1) distribute the negative sign to each term in the second parentheses

(7x-10)-(-6x-8)

7x-10+6x+8

2) combine like terms

7x+6x= 13x

-10+8=-2

13x-2
