Answer:
I believe it's 122? You take the area if it were a full square and then subtract the missing area using the other measurements
-2x^3 - 2x^2 + 12x
= -2x (x^2 + x - 6)
= -2x(x + 3)(x - 2)
Its D
Answer:
Yes
Step-by-step explanation:
It is a Pythagorean Triple. A Pythagorean Triple is the sides of a triangle that fit perfectly into the Pythagorean Theorem, which is:
a²+b²=c²
12, 13, and 15 are numbers that you should know off the top of your head so if you see a triangle with 2 of those numbers, you instantly know the 3rd number.

71/2 can also be written as 15/2, so divide 15/2 by 3/4. When you divide fractions you flip the second fraction and multiply it, so now it would be 15/2 X 4/3, so you would get 60/6 which is 10!
