(3r - 2)(3r - 2) or (3r - 2) squared.

-1r

if you have 12r and you minus 4r it doesn't equal 48. it would equal 8r to find out what r is i would have to see the whole problem

- 6r - 5 = 7 - 12r add 12r to both sides 12r - 6r - 5 = 7 - 12r + 12r 6r - 5 = 7 add 5 to both sides 6r - 5 + 5 = 7 + 5 6r = 12 divide both side integers by 6 r = 2 ---------- check in original equation -6(2) - 5 = 7 - 12(2) - 12 - 5 = 7 - 24 - 17 = - 17 checks

12r-20

12r - 20

12r + 4 = 112, 12r = 108, r = 9

It is 12r - 20 or 4*(3r - 5)

The expression is: 12r-20 when simplified

-6r-5 = 7-12r 12r-6r = 7+5 6r = 12 r = 2

r - 12 â‰¥ 5r - 12 + 12 â‰¥ 5 + 12r â‰¥ 17

12r - 15s - r + 3s = 11r -12s
