Question

Given A =1/2(b1 + b2)h, solve for h?

Answer 1

I know that you have to isolate h.

Answer 2

okay good
now remember PEMDAS?

Answer 3

yes sort of but would i distribute 1/2?

Answer 4

yes, because you have to take away the P in PEMDAS first which is parentesis.

Answer 5

ok so where would "A" go. Would you have to subtract it by 1/2

Answer 6

its easier to show you then explain..will you let me?

Answer 7

sure please do

Answer 8

okay.
A =1/2(b1 + b2)h
A =(b1 + b2)h (2)
2*A= (b1+b2)h

2*A= (b1+b2)h /(b1+b2)

\[2A \div (b1+b2)= h\]

Answer 9

does that help?

Answer 10

ok so wait how did you get this again: A =(b1 + b2)h (2). did you distribute?

Answer 11

I times two on both sides to get rid of 1/2

Answer 12

to get 2A

Answer 13

oh ok got it. I understand now thanks! :)

Answer 14
