This is basically asking for the surface area so knowing that is a cube all the sides are equal so one side would be 16(16) which is 256 in ^2. The knowing that there is 6 sides you would multiply it by 6 which is 256(6)= 1536^2
I'm pretty sure its B. (9x2+2x-7)(x)+(9x2+2x-7)(-4) Because its just splitting up the (x-4) and if you add the answers together then you get the same answer as the original<span />
