4x^2+ 8xy - 60y^2 =48x^3y^3
Answer:
$33.75
Step-by-step explanation:
3 ft are in a yd so 9 ft are in 3 yd. Then you multiply 9 by 3.75 which brings you to the answer $33.75.
We can get the answer to this equation by solving for the variable (r).
7.4 - 9 - 2r = 18
We want to get r on one side, so we want to push everything else to the other side.
-2r = 18 - 7.4 + 9
-2r = 19.6
2r = -19.6
r = -9.8
