If that's 3r + 12, that factors to 3(r + 4)

3r + 3r + 2t = 6r + 2t

-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r

5

3r-r equals 12 = -9

(3r + 18)/12 = (4r - 48)/4Multiply both sides by 12: (3r + 18) = 3*(4r - 48)or: 3r + 18 = 12r - 144Subtract 3r from both sides: 18 = 9r - 144Add 144 to both sides: 162 = 9rDivide both sides by 9: 18 = rAnswer: r = 18

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

No, it's simply 3r, because multiplication (r multiplied by 3) comes first in the order of operations.

-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r

(3r + 2)(r - 5)

If: -5 = 7+3r then the value of r works out as -4

-2r(3r - 11)(3r + 11)
