It would be best to keep it the same. So if I knew the hypotenuse was 9 and that one side was 4 and I was looking for the other one I would right it like this:

4^2 + B^2 = 9^2
Then simplify
16 + B^2 =81
Then subtract
B^2 = 65
And then take the square root of both sides
<span>B = 8.0622577483 (since I came up with random numbers it ended up so uneven :P)

Does that make sense to you? I hope that helped you to understand! Feel free to let me know if you have any questions!

I didn't mean to post the answer and can't figure out how to take it down. Somebody report it so it does go down and the question can be later answered. Thank you

Answer:

The value of x will be:

$x=-5$

Step-by-step explanation:

Given the equation

$4-2(x+7)=3(x+5)$

Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.

$4-2x-14=3x+15$

simplifying the equation by subtracting 14 from the L.H.S

$-10-2x=3x+15$

Subtracting 15 from both sides

$-10-2x-15=3x+15-15$

$-25-2x=3x$

combining the like terms

$-25=3x+2x$

$-25=5x$

dividing both sides of the equation by 5

$\frac{-25}{5}\:=\:\frac{5x}{5}$

$-5=x$

Therefore, the value of x will be:

$x=-5$
