Answer:
38 feet
Step-by-step explanation:
P(x) = ℓ(x) + ℓ(x) + w(x) + w(x)
= x + x + (4x - 1) + (4x - 1)
= (x + x + 4x + 4x) + (-1 -1)
= 10x - 2
P(4) = 10(4) -2 = 38
The perimeter is 38 feet when the length is 4 feet long, so Cho will need to
cover 38 feet with garden stones.

Given: Right angles are 90 degrees.
if-then: If it is a right angle, then it's 90 degrees.
Converse: If the angle is 90 degrees, then it's a right angle.
Inverse: If it is not a right angle, then it's not 90 degrees.
Contrapositive: If the angle isn't 90 degrees, then it's not a right angle.
Bi-conditional: It is a right angle if and only if it's 90 degrees.
81 servings. I found this by making a ratio:
24 c 108 c
------- = -------
18 ser x
I then cross multiplied to get the equation: 24x=1,944. I solved this equation to find x, the number of servings in 108 cups, which was 81.
I remember doing this back in elementary school. I had a hard time with it too!
