The square of a binomial expands as follows:

Expanding all the binomials, we have

Sum like terms:

Simplify terms appearing on both sides:

Move all terms involving k to the left and all numbers to the right:

Divide both sides by -20:

Slope: 15 Y Int:40 equation y=15x+40. 24 Hours $55
The original price was $500
First we find 15% of what is $75
15/100 x N =$75
n = $7500/15
n = $500
