7x7(12+9) to the power of 3
1 is 28
2 is 13, 84, 85
Figure both by the Pythagorean Theorem<span />
The answer for the question is 20.25
5x – 1 = 3x – 15
Subtraction Property of Equality (Subtract 3x from both sides)
2x - 1 = -15
Addition Property of Equality (Add 1 to both sides)
2x = - 14
Division Property of Equality (Divide both sides by 2)
x = -7
