7x - 3x = 24
The 7x and the 3x are both like terms, so they can be combined. 7 - 3 is 4, so the equation turns into
4x = 24
Now, you want to get the x alone, so you divide both sides by 4 because it is the opposite of multiplication. 24 divided by 4 is 6, so
x = 6

in.
Step-by-step explanation:
The Pythagorean Theorem is as follows:
(We know the length of the legs, or a and b, so we can use the formula to find the length of c, or the hypotenuse)
(Simplify)
(Take the square root of both sides)
in.
