Question

Did i do this right?

Answer 1

P=a+b+c ; for A

Answer 2

i got P-b-c=a

Answer 3

that is correct

Answer 4

thank you

Answer 5

But how would i do
A=1/2bh;solve for h ?

Answer 6

@robz8

Answer 7

\[\frac{ 2A }{ b } = h\]


you divide by 1/2 on both sides, then divide by b on both sides

Answer 8

same thing as adding and subtracting, except you multiply and divide

Answer 9

oh wow thank you i understand

Answer 10

you're welcome!

Answer 11

Sorry for so many questions (i probably have a few more coming) but did i do this right? \[S=2\pi rh+2\pi r ^{2}\] ;solve for h

Answer 12

[S-2\pi r ^{2}/ 2\pi r = h\]

Answer 13

\[S-2\pi r ^{2}/2\pi r =h\]
