How much space is on an shape
<span>2x(x - 3)(x + 2)
= </span><span>2x(x^2 - 3x + 2x - 6)
</span>= 2x(x^2 - x - 6)
= 2x^3 - 2x^2 - 12x
The symbol "<=" without quotes means "less than or equal to"
-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2
y <= 3x + 21
So the answer is choice D
The answer to that question is 250.
