Given:
<span>Tiana can clear a football field of debris in 3 hours. </span><span>
Jacob can clear the same field in 2 hours.</span>
<span>
Number of hours to complete the Job.
Tiana - 3 hours
Jacob - 2 hours
Tiana and Jacob - t
Work done per hour:
Tiana = 1/3 per hour
Jacob = 1/2 per hour
Tiana and Jacob = 1/t
Their combine work should have this equation:
1/3 + 1/2 = 1/t
(1/3*2/2) + (1/2*3/3) = 1/t
2/6 + 3/6 = 1/t
5/6 = 1/t
t(5/6) = 1
t = 1 * 6/5
t = 6/5
t = 1.20 hours
60 minutes * 0.20 = 12 minutes
1.20 hours </span>→ 1 hour and 12 minutes.
<span>
It would take 1 hour and 12 minutes if they decide to clear the field together.

Answer:
8x + 6
Step-by-step explanation:
Perimeter is the distance round a figure.
A rectangle has 4 sides, opposite sides being equal.
(2x+3) + (2x+3) + 2x+2x = perimeter of the rectangle
4x+6 + 4x =
8x + 6 = perimeter of the figure

Hope this helps and if it does please mark as brainiest answer thx.
Answer: a and d
Step-by-step explanation:
(to find all points of discontinuity, set denominator equal to zero and solve)
(to factor, find two numbers when added together equal -7 and when multiplied together equal 10)
-2 + -5 = -7
-2(-5) = 10
-2 and -5 are the two numbers
The area of the rectangle would be 45 m^3
