Which correctly shows the area formula for a trapezoid, A=12h(b1+b2), rearranged for the quantity of interest h?
To rearrange the area formula for the quantity of interest h, you would divide both sides of the equation by 12(b1+b2):
A = 12h(b1+b2)
Dividing by 12(b1+b2) on both sides:
A / (12(b1+b2)) = h
Therefore, the correct formula rearranged for the quantity of interest h is:
h = A / (12(b1+b2))
To rearrange the formula A = 12h(b1 + b2) for the quantity of interest h, you need to isolate the variable h. Here's the step-by-step process:
Step 1: Divide both sides of the equation by 12:
A/12 = h(b1 + b2)
Step 2: Divide both sides of the equation by (b1 + b2):
A / (12(b1 + b2)) = h
Therefore, the correct rearrangement of the formula is:
h = A / (12(b1 + b2))
To rearrange the formula A = 12h(b1 + b2) for the height h, we need to isolate h on one side of the equation. Let's go through the steps:
1. Start with the formula: A = 12h(b1 + b2)
2. Divide both sides of the equation by 12 to isolate h: A/12 = h(b1 + b2)
3. Now, we want to isolate h, so divide both sides of the equation by (b1 + b2): (A/12) / (b1 + b2) = h
Therefore, the formula rearranged for the height h is h = (A/12) / (b1 + b2).
