At another theater, workers have to cut a new trap door. The door can be no more than 145 square feet in area, with whole-number side lengths. They have to bring in 3 items to the stage. The first item is 7 feet 5 inches wide and 6 feet 9 inches long. The second item is 13 feet 4 inches wide and 9 feet 8 inches long. The third item is 5 feet 6 inches wide and 10 feet 4 inches long. What size of trap door would you recommend? What is the perimeter of your trap door?

you should pay $0.88

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
