A rectangular pool is in a backyard. The length of the pool is 3 times the width of the pool (x). Theres a pool deck around the pool that is represented by the binomial 3x²+24x feet. If the area if the pool deck is 720 square feet, what are the dimensions of the pool deck? what are the dimensions of the pool?

you can use a^2+ b^2=c^2

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
