You can simply put the equation as 9x = 36 and divide by 9, then x = 4
The expression would be 32+3x where x represents the cost of each shirt. If the shirts were $9 each max would have spent $59
The volume of the refrigerator would be 30
.65 because 3/5 is equal to .6
For the first question, simply plug in the value of 3 into the polynomial question. The final answer is your volume of the hot water tub.
For the second question, you can figure out that x = -5 is not a real root because it does not touch or cross the x axis.
If it does it would be an solution.
