Take 28% of 500 which is 140 then add that to 500.
The answer is 640.
V = lwh
V = (x + 2)(x + 3)(x)
V = (x)(x^2 + 3x + 2x + 6)
V = (x^3 + 3x^2 + 2x^2 + 6x)
V = x^3 + 5x^2 + 6x
All you do is foil the dimensions together and then combine like terms. Hope this helps!
To complete the square of a polynomial, use the term "(b / 2) ^ 2".
In this polynomial, the "b" term is 14.
Plug that in.
(14 / 2) ^ 2
7 ^ 2
49.
The answer is C.

Answer:
4x^{3} + 6x^{2} -10x -15
Step-by-step explanation:
(2x+3)(2x^{2} -5)
2x × 2x^{2} + 2x× (-5) + 3× 2x^{2} + 3 ×(-5)
=4x^{3} -10x + 6x^{2} -15
= 4x^{3} + 6x^{2} -10x -15
