Question

Solve by taking square roots
-8+36r^2=1

Answer 1

first you'd have to get -8 to the right

Answer 2

so add 8 to both sides.. i got 36r^2=9

Answer 3

Yes, any idea what to do next?

Answer 4

divide 36

Answer 5

yea divide 9 by 36

Answer 6

.25?

Answer 7

Yep.
So now we have \(\Large r^2=\frac{1}4\)

Answer 8

The last step would be take the square root of both sides to solve for r

Answer 9

and how would i get an answer to that?

Answer 10

\(\Large\sqrt{0.25}\)

Use a calculator

Answer 11

.5

Answer 12

yep :)

So \(\Large r=\frac{1}2\) (or 0.5)

Answer 13

Goodness, thank you so much! :D

Answer 14
