Answer:
The other base is 8 feet.
Step-by-step explanation:
You need to recall the area of a trapezoid equation:

We need to work back, so we need to divide the area by 6:
60 ÷ 6 =
= 10
Then we need to multiply this by two to find a + b value:
10 x 2 = a + b
20 = a + b
Beause we know the value of a, which is 12, we can factor this in:
20 = 12 + b
Move the +12 over to the other side, making it a negative:
20 - 12 = b
8 = b
<h3>So the other base is 8 feet!</h3>

Answer:
Step-by-step explanation:
y= -3x+1
you use inverse operations, and since you want the y alone, you subtract 3x on both sides, giving you y= -3x+1
Answer:
20 feet
Step-by-step explanation:
1st piece = x
2nd piece = 2x
3rd piece = 6x
x+2x+6x=180
9x=180
x=20
so the first piece is 20 feet, the second is 40, and the third is 120.
