Answer:
A=384 
Step-by-step explanation:
A =2(wl+hl+hw)
A=2(8*8+8*8+8*8)
A=2(64+64+64)
A=2(192)
A=384

39-A
When you multiply 8 times 2 its 16 and 40-16 is 24
40-D
less than is towards the negatives and for less than or greater than you use open circles
Answer:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)
Step-by-step explanation:
The volume of a rectangular prism of length L, depth W and height H is
V = L * W * H.
Thus,
in this case,
V = (2x + 1)(x - 2)(3x).
The order in which we multiply these quantities together is immaterial.
Working from left to right, we get:
V = (2x^2 - 3x - 2)(3x), and then:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)
