Answer:
answer: B
Step-by-step explanation:
The least common multiple of 5 and 12 is 60.
The equation for the leg length, y is y = (P - 2x - 4)/2
The length of the leg "y" is 3 feet
a) Given the perimeter of the trapezoid expressed as:
P=2x + 2y + 4.
We are to make <em>y the subject of the formula </em>as shown:
P = 2(x+y) + 4
P - 2x = 2y + 4
P - 2x - 4 = 2y
Swap
2y = P - 2x - 4
y = (P - 2x - 4)/2
Hence the equation for the leg length, y is y = (P - 2x - 4)/2
b) Give that P = 26 feet and x = 8feet
y = (P - 2x - 4)/2
y = (26 - 2(8) - 4)/2
P = 26-20/2
P = 6/2
y = 3 feet
This shows that the length of the leg "y" is 3 feet
