Answer 1

Answer:C

Explanation:

Answer 2

Answer: C

Explanation:

To find b₂, we need to use our algebraic properties to isolate b₂.

`A=(1)/(2)h(b_1+b_2)` [multiply both sides by 2]

`2A=h(b_1+b_2)` [divide both sides by h]

`(2A)/(h) =b_1+b_2` [subtract both sides by b₁]

`b_2=(2A)/(h)-b_1`

Now, we know that C is the correct answer.
