Question

Which are equivalent equations ? Check all that apply.

Answer 1

Answer:

A) and D) are correct.

Step-by-step explanation:

a = 1/2(b1 +b2)h

Let's find b1

2a = (b1 + b2)h

2a/h = b1 + b2

b1 = 2a/h - b2

Now let's find h.

a = 1/2(b1 + b2)h

2a = (b1 + b2)h

h  = 2a/(b1 + b2)

Therefore, A) and D) are correct.

Hope this will helpful.
