The area of a trapezoid is 144 square inches. if the height is 12 inches, find the length of the median.
deff fn [24]

Answer: 12 inches

Step-by-step explanation: In this problem, since we're asked to find the length of the median, let's use our formula for the area of a trapezoid that involves the median which is shown below.

Area = median · height

We know that the area is 144 and the height is 9 so we can set up the equation 144 = M · 12. Now to solve for <em>m</em>, we divide both sides of the equation by 12 and we find that 12 = M.

So the length of the median of the trapezoid is 12 inches.

Y and x have a proportional relationship, and y = 24 when x = 16 What is the value of x when y = 36?
lozanna [386]
To solve, we need to know by how much y increase to know how much to increase x by:

First step, divide the new value, 36 by the original 24:

36/24 = 1.5

Now, multiply the 1.5 by the x to get the new increase value:

16 x 1.5 = 24 

So, x= 24 when y= 36

Hope this helps!
