Weegy: 4t+2u -u , where t = 2 and u = 1
4(2)+2(1) -(1)?

|r + 3| 7
Weegy: for values of r + 3 ? 7, |r+3| = r+3
for values of r + 3 < 7, |r+3| = -(r+3) = -r-3
so for values of r ? 4, solve for r + 3 ? 7
so r ? 4. [ That is all values greater than equal to 4
for values of r < 4, solve for - r - 3 ? 7
-r ? 10
r ? -10
so all values less than or equal to -10
so to sum it up, the answer is r ? -10, and r ? 4 ]
