Use the Pythagorean Theorem of a² + b² = c² to solve for x.
x² + (x + 3)² = (√117)²
x² + x² + 6x + 9 = 117
2x² + 6x + 9 = 117
2x² + 6x + 9 - 117 = 0
2x² + 6x - 108 = 0
2x² + 18x - 12x - 108 = 0
2x(x + 9) - 12(x + 9) = 0
(2x - 12)(x + 9) = 0
x = - 9, 6
Length cannot be negative so you can't use - 9.
x = 6. Option C is your answer.

Step-by-step explanation:
c^2*b
We know that c is 3, and b is 5, so we can substitute them in
3^2*5
Solve the exponent first
9*5
Multiply

Answer:
Ok, lemme say something.
4.5 shoes are for 9 inch feet.
Dont think a 6 foot person is gonna fit tbh.
Step-by-step explanation:
A shoe size is for relation to feet size. Your feet grow from your height too, along with weight. If you are 6 feet, your feet are gonna be more than at least 1 foot.
4.5 shoes are for 9 inch feet
1 foot = 12 inches.
12 > 9.
12-9=3.
Yes, by 0.001. Thank me later.
