Solve 8r-2(r 9)=-60

Evaluate

8 r - 2 (r \times 9) = - 60

Evaluate

More Steps

- 10 r = - 60

Divide both sides of the equation by - 10

r = 6

Square both sides of the equation

r^{2} = 6^{2}

To covert the equation to rectangular coordinates using conversion formulas,substitute x^{2} + y^{2} for r^{2}

x^{2} + y^{2} = 6^{2}

Solution

x^{2} + y^{2} = 36
