B It’s the one that makes sense
Find f(-2) f(x)=9x^2-5x+2
f(-2) means replace x in the equation with -2:
f(-2)=9(-2)^2-5(-2)+2
= 9(4) +10 + 2
= 36 +10 + 2
= 48
f(-2) = 48
Answer:
Step-by-step explanation:
Volume = L × W × H
Length L = 17in
Width W = 7in
Height H = 7in
Volume V = 17×7×7
V = 833
Volume = 833 in^3
Not as hard as you think.
Just multiply all the prime factors together.
