Answer:
72
Step-by-step explanation:
The formula for surface area is SA = 2lw + 2wh + 2lh
W = width
L= length
H = height
A = 2(wl + hl + hw)
2·(6·3+2·3+2·6)
Simplify that down to get the answer 72
5/2
8
If the only zero for this function is at x = - 4 it looks like this:
f(x) = (x+4)(x+4) = x^2 +8x + 16 <u> so j = 8 </u>
your answer is B
