Answer:
d. 18a² - 12a
Step-by-step explanation:
f(x) = 2x² + 4x
f(-3a) = 2(-3a)² + 4(-3a)
2(-3a)² + 4(-3a)
2(9a²) + (-12a)
18a² - 12a
Answer:
Perimeter of XYZ = Perimeter of QRP
Step-by-step explanation:
Since congruent then
P of XYZ = P of QRP
X * (x + 10) = y - 40
(x + 2)(x + 12) = y
x^2 + 10x = x^2 + 14x + 24 - 40
10x = 14x - 16
-4x = -16
x = 4
4 + 10 = 14
