Answer: 12 feet.

Step-by-step explanation:

Use the Pythagorean theorem to solve:

$a^2 + b^2 = c^2\\5^2 + b^2 = 13^2\\25 + b^2 = 169\\b^2 = 144\\b = 12$

The third side length is 12.

Which equation has no solution?

dybincka [34]

So, we start with this.
$5+2\left(3+2x\right)=x+3\left(x+1\right)$
Simplify.
$4x+11=4x+3$
Subtract 11 from both sides.
$4x+11-11=4x+3-11$
Simplify.
$4x=4x-8$
Subtract 4x from both sides.
$4x-4x=4x-8-4x$
Simplify
$0=-8$
This equation has no solution, the answer would be B!
Have a nice day! :)
