Answer:

Step-by-step explanation:

The secret trick to factoring is the greatest common factor.

The greatest common factor of 9 and 21 is 3. Thus, our expression is

3(3 + 7).

The greatest common factor of 14 and 28 is 7. Our expression is

7(2 + 4)

The greatest common factor of 80 and 56 is 8. This makes our expression

8(10 + 7).

Find the value of x.

Cerrena [4.2K]

$x^2 + (x + 3)^2 = (\sqrt{117})^2$

$x^2 + x^2 + 6x + 9 = 117$

$2x^2 + 6x -108 = 0$

$x^2 + 3x - 54 = 0$

$(x + 9)(x - 6) = 0$

$x + 9 = 0 ~~or~~ x - 6 = 0$

$x = -9 ~~ or~~ x = 6$

Since the side of a triangle cannot have a negative length, we discard the solution x = -9.

Answer: x = 6
