I confused ! I don't get what your trying to say please explain better !
Answer:
x(x+3)(x-2)
Step-by-step explanation:
you can't multiply any of them so the expression is that. x cannot be multiplied with x+3 because x+3 are together.
First question should be X=9
The second should be X=15
Is -2 the only point of reference given?
The proper equation used to solve this is (let's use E for edge) E=V^1/3
The V stands for volume. So, your equation is 512^1/3
Your answer is 8, which is what you get when you work this out.
