24x-48 because you multiply the 8 with 3x and 8 with -6
At a certain company, 64.5% of the employees have engineering degrees.
To express the percentage as a decimal we need to remove the % symbol.
To remove % symbol we always divide by 100
When we divide by 100 we move the decimal point two places to the left.

The decimal vale of 64.5% is 0.645
A^2 + b^2 = c^2
20^2 = 400
52^2 = 2704
400 + b^2 = 2704
2704 - 400 = 2304
So you need the square root of 2304 which is 48 so the length of the other leg is 48 ft.
