Question

Please help. No one is helping me :(
Rewrite the formula. Solve the area of the trapezoid formula for one base.

So pretty much make the equation start with b1=

Answer 1

is there a picture?

Answer 2

No.

Answer 3

I have to solve for one base, but make the area of the trapezoid equation stay the same.

Answer 4

well im not quite sure how to figure that out srry

Answer 5

Well, another similar problem I figured out is solve the slope intercept equation y=mx+b for the slope, m.

y=mx+b subtract b to both sides
y-b=mx divide by x to both sides
y-b/x=m

I have to do something like that to the area of the trapezoid formula.

Answer 6

Area of trape....= 1/2 (b1+b2)h
Now u just have to make b1 the subject of the formula, can u do it now?

Answer 7

i don't know hot to make the b1 alone..

Answer 8

Rearrange the formula so:
2A = (b1 + b2) h
(2A) / h = b1 + b2
b1 = ((2A) / h) - b2
