Answer: correct answer is B.(2x+3y)(4x^2-6xy+9y^2)
8x^3 + 27y^3
(2x)^3+(3y)^3
(2x+3y)(4x^2-6xy+9y^2) <----answer
2x+2x+60=180 because the angles have to add up to 180
So you have
4x+60=180
4x=120
x=30
The answer is z = 4 because of you put 4 into the equation it equals to 100
The maximum length is 5 . The 3 tall takes away from the 8 and then your left with 5.
