You get the hypothenuse by doing √a²+b² = c
So....
Square both terms
x² + (3x+3)² = 625
x² + 9x² + 18x + 9 - 625 = 0
10x² + 18x - 616 = 0
x₁,₂ = (-b±√Δ)/2a
Δ = b²-4ac
You call a 10, b 18 and c -616
x1,2 = (-18±√18²-4*10*-616)/2*10
x1,2 = (-18±√324+24640)/20
x1,2 = (-18±√24964)/20
x1,2 = (-18<span>±158)/20
x1 = -18+158/20 = 140/20 = 7
x2 = (-18-158)/20 = -176/20 = -44/5
Pick the first solution
So one leg is 7 and the other is 3(7+1) = 3(8) = 24
Let's verify </span>√24²+7² = √576+49 = √625 = 25
The board is 6 feet long, and there is 12 inches in a foot. This means the board is 72 inches long. Each piece she cuts is 1/4 (3) inches long. This means if we do 72/3, we see the number of pieces Joanna cuts is 24.

Step-by-step explanation:
mulitply all the numbers by each other
A line that passes through 2 points on a circle is called a secant not to be confused with chord which is a segment not a line.
