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.

Answers:
1. No I don't agree with Selena because the area of the rectangle has the exact same area of the square
Step-by-step explanation:
1. square = x
rectangle length = 6 + x
rectangle width = x - 6
the plus 6 and minus 6 cancel each other out and make the same area that the square has.
Im sorry i dont know what the answe to 2 is.
We have that
<span>f(x) = 3x + 2
</span><span>g(x) = x - 3
[</span>g(x) - f(x)]=(x-3)-(3x+2)--------> (x-3-3x-2)-----> -2x-5
the domain is all real numbers
the answer is
<span>–2x – 5; all real numbers</span>
