Answer:
63 sq ft
Step-by-step explanation:
The formula for the area of a trapezoid is
A = h(a + b)/2 where a and b are the lengths of the parallel sides and h is the distance between them
A = 7(11 + 7)/2
= 7(18)/2
= 63 sq ft
Y - x = 6
y + 2x = 57
2y - 2x =12
y + 2x = 57
∴3y = 69
y = 23
23 - x = 6
-x = -17
x =17
large van = 23
small van = 17
Answer:
x=5
Step-by-step explanation:
its easy just subtract 9 from 24 to get 15 and 15 divided by 3 is 5
Answer: 0
