Answer:
Copy the picture down.
F=6cm
G=8cm
F=6 G=8
Step-by-step explanation:
ABCE-ABCD=ADE
ADE=12cm²
AD=6cm
48/6=8
f=6
g=8
I think it would be 55
a=72° b = 6°
answer is in pic
f(x) = 2x^3 - 4x.....find f(-2).....so sub in -2 for x
f(-2) = 2(-2^3) - 4(-2)
f(-2) = 2(-8) + 8
f(-2) = -16 + 8
f(-2) = -8 <==
