Step-by-step explanation:
1) = {5(x+y)} - 2x
= 5x + 5y - 2x
= 3x + 5y
2)= {2(p×q)} + (p×q)
= (2p×2q)+ p×q
= 4pq + pq
= 5pq
3)= 6a + (8b + 2a)
= 8a + 8b
= 8(a+b)
4)= 3x² + ( x²+7x)
= 4x² + 7x
= x(4x+7)
Answer: 3 yd

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>
