I think is B, because HL is only for right triangles
A flat circular plate has the shape of the region x 2 + y 2 ≤ 1. points on the plate have temperature t(x, y) = x 2 + 2y 2 − x. find the temperatures of the hottest and coldest points of the plate
To find the answer, you do these steps.
1) Simplify the brackets.
5 - x - 5 > -2(x + 4)
2) Put 5 - x - 5 as -x
-x > -2(x + 4)
3) Solve x + 4
-x > -2x - 8
4) Add 2x to both sides of equation.
-x + 2x > -8
5) Do -x + 2x to x
x > -8
Your answer is A.
