Rewrite the equation 3r - 6 = 39 by factoring the side that contains the variable r.

r=15

Step-by-step explanation:

If I'm understanding this correctly, you would add 6 to the right side of the equation which would make it 3r = 45. Then you would divide 45 by 3, equaling 15. So that ends up with r = 15.

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

this doesn't make sense lol
