54
Step-by-step explanation
(area of mat subtracted from area of room)-center of mat to wall
50 x 20 = 1000, 20 + 36 = 56 so 56 hours
If you would like to factor the expression 36y^2 - 84y - 147, you can do this using the following steps:
<span>
36y^2 - 84y - 147 = 3 * (12y^2 - 28y - 49) = </span>3 * (6y + 7) * (2y - 7)
The correct result would be b. <span>3 * (6y + 7) * (2y - 7)</span>.
