Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
× 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches
(4 1/3 * (-1) * 5) / 12 = -1.80555556
They are both equivalent to 1, so they are equal.
Answer:
14cm
Step-by-step explanation:
To find volume, you need to multiply the height width and length together. So when you have one missing measurement, to find it, you need to do the same steps except for put a variable for the missing measurement. And continue to do the problem as you would. Here is how I solved it.
V=12x18xH
3024=216xH (216 is 12x18)
Then to find the missing side, do 3024/216 which equals 14.
