By using the Pythagorean Theorem, we know that the length of the slide is 17 ft.

Step-by-step explanation:

We can use the Pythagorean Theorem to solve this equation.

a = 8

b = 15

Now, let's plug in these numbers so we can know the length of the slide.

So, the length of the slide is 17 ft which is answer choice C.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
