Answer
Find out the length of the second parallel side.
To prove
Formula

Where a , b are the parallel sides of trapezoid and h is the height of the trapezoid.
As given
The area of a trapezoid is 132 cm².
The height is 12cm and the length of one of the parallel sides is 9cm.
Here h = 12cm
a = 9cm
Put in the formula

132 × 2 = 9 × 12 + 12b
264 = 108 + 12b
264 - 108 = 12b
156 = 12b

b = 13cm
Therefore the length of the second parallel side is 13cm.
The answer for x is 9/13. Hope it help!
Division property of equality
5 less than (-5) of 1/4 of my age (age/4) is 12 (=12)
-5+a/4=12
add 5 to both sides
a/4=17
times 4 both isdes
a=68
your age is 68
Answer:
x = 1
Step-by-step explanation:
4x + 6 - x = 7 + 2x
3x + 6 = 7 + 2x
3x - 2x = 7 - 6
x = 1
