Y = 1 3 -x = left[y \right] = \left[ 3-x\right][y]=[3−x]
The answer would be -81t^2+16
D is the answer
(4+8)+1 = 13
4+(8+1) = 13
Therefore equation D is true
2(4x - 9) =
2 * 4x - 2 * 9 =
8x - 18
Hope this helps!!

4b - 7 + 2b + 11 and b + 3 + b + 1 are congruent.
You add the common factors in each problem: 2b + 4 = 2b + 4
