Answer:
f(g) = -15x^2 + 15x + 2.
g(-2) = 18.
Step-by-step explanation:
f(g) = -5(3x^2 - 3x) + 2
= -15x^2 + 15x + 2.
g(-2) = 3(-2)^2 - 3(-2)
= 12 + 6
= 18.
Answer:x=-8
Step-by-step explanation:subtract 21 from both sides then simplify 31-21 to -8
Answer:
Which are equivalent expressions?
Check all that are true.
y + x = 2x
x + x + x + x = 4x (true)
x + x = 2x (true)
x + y + y + x = 2x + 2y (true)
x + y + x + x = 2x + y
