<h3>
Answer: 11x + 6y + 11</h3>
=========================================
Work Shown:
To find the perimeter, we add up all the exterior side lengths.
P = perimeter
P = (side1) + (side2) + (side 3)
P = (2y-3x-3) + (12+5x+7y) + (9x-3y+2)
P = (-3x+5x+9x) + (2y+7y-3y) + (-3+12+2)
P = 11x + 6y + 11
Answer:
Length: 16 feet
Width: 25 feet
Step-by-step explanation:
Alright so let's set up our system:
The area of a rectangular patio is 400 square feet.: L*W = 400
The length of the patio is 9 feet more than its width: L = W - 9
If you look here, all we need to do now is plug in L and solve.
(W - 9)W = 400
W^2-9W - 400 = 0
You can attempt to factor this in a number of ways. I recommend a factor tree, but however you do that is fine.
(W + 16)(W - 25) = 0
so we have two W values now, 25 and -16. Which one do we pick? We pick 25, because we cannot have a negative Width. That would literally break the universe.
So now we plug in 25 in our second equation to get L:
L = 25 - 9
L = 16
And now we have both our answers!
