Answer:
please post a more cohesive question. The values are very confusing
<u>3x + 65 = 7x + 13</u>
Here's one way:
Subtract 3x from each side: 65 = 4x + 13
Subtract 13 from each side: 52 = 4x
Divide each side by 4 : <em> 13 = x</em>
The Answer would be: Ratio
20.808 would be the diagonal, or, also known as, the hypotenuse. We use pythagorean theorem for problems like these.
