Question

r squared+ 9 squared=(6+r)squared

Answer 1

\[r^2+9^2=(6+r)^2\]

Answer 2

Correct?

Answer 3

Did I type the question correctly?

Answer 4

Well, your not responding. So, I'm gonna continue assuming that is the question.

Answer 5

Further simplify the expression to
\[r^2+81=36+12r+r^2\]

Answer 6

Cross out the r^2 as it is in both sides.

You are left with 81=36+12r

Subtract 36.

45=12r

Solve for r now.
