**Step-by-step explanation:**

The Pythagorean Theorem, which provides us with the relationship between the sides in a** right triangle**. A **right triangle** consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle.

**Step-by-step explanation:**

h varies directly with a and inversely with b.

2 is the constant of variation.

The answer is D. this is because in order for the brackets to equal zero, you have to have a negative number inside.

Do you need to solve for x?

As the both equal y, they must both equal each other so

-2x+7=5x-7

Add 2x to both sides

7=7x-7

Add 7 to both sides

14=7x

Divide both sides by 7

2=x

X=2
