4(x-2)=-72
Multiply the bracket by 4
(4)(x)(4)(-2)=-72
4x-8=-72
Move -8 to the other side. Sign changes from -8 to +8.
4x-8+8=-72+8
4x=-64
Divide by 4 for both sides.
4x/4=-64/4
x=-16

Answer:
408
Step-by-step explanation:
Surface area formula is A=2(wl+hl+hw)
Substituting these values into the formula you would get
2·(3·8+4·8+4·3)=136
136 accounts for one rectangular prism.
Since you have 3 multiply 136 by 3 which would leave you with 408
