Question

24 POINTSSS for anyone who answers The of a square garden is 36x^2 -60+25 find the perimeter if x=3

Answer 1

If x=10, the answer would be 220ft

Explanation:

All the same, steps until you get to 24(x)-20. This time x would equal 10 so it would be 24(10)-20. Which would equal 220, or 220ft.

Answer 2

The perimeter is 52

Explanation:

The area is 36x^2 -60x+25

We set this equal to 0 to find the length and width

A= 36x^2 -60x+25

We notice that this is a perfect square trinomial

(a^2 -2ab-b^2) = (a-b)^2

let a = 6x and b=5

A=(6x-5) (6x-5)

The length and width are the same since is it a square (we know it is a square so they have to be equal)

The perimeter of a square is

P =4s

P =4 (6x-5)

Distribute the 4

= 24x -20

Let x =3

P = 24(3) -20

=72 -20

= 52

The perimeter is 52
