Answer:
d
Step-by-step explanation:
This is the concept of algebra, given that the area of a rectangular pool is (15x-9), the possible dimensions of the pool by factoring will be:
Area=length×width
Area=(15x-9)
factoring the above we get:
Area=3(5x-3)
therefore the possible dimension will be:
length=5x units
width=3 units
It would be 7 with 75 over 100....it would look like 7 75/100. then simplify it.
$30 because you are taking away 20% of $30 and then adding back that 20%.
