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:
x²+12x+36 =0
Step-by-step explanation:
Hii, so I'm assuming your equation is equal to 0-->
x²+_x+36 =0
this could go many ways..
x²+12x+36 =0
which factor to (x+6)(x+6)
x²+15x+36 =0
which factor to (x+12)(x+3)
x²+13x+36 =0
which factor to (x+9)(x+4)
If I had to choose a answer.. I would go with the 1st option x²+12x+36 =0
Hope this helps, if there was more to this question, leave a comment and I can come back and help you ;)
The Correct answer is 3
Explanation:
Using the defined function, f(a) will produce the same result when substituted for x:
F(x)=x^2-x^3
Setting this equal to 4, you can solve for a:
a2 – 5 = 4
a2 = 9
a = –3 or 3
Answer:
=8x+4
Step-by-step explanation:
=2(4x+2)
a=2,b=4x,c=2
=2 x 4x + 2 x 2
Simplify- 2 x 4x + 2 x 2: 8x + 4
