Answer:
Third option is correct: 1 / (t+4)^2
Step-by-step explanation:
This equation can be written as the following:
(t+3)/(t+4)*(1/t^2+7t+12)
We know this because of the division of fractions. For example:
(1/y)/(1/x) = (1/y)*(x/1)
Now that we know this, we can advance.
Now we have to try to factor (t^2+7t+12)
We can make this into (t+3)(t+4)
Ah! Perfect! There is a t+3 in the denominator of the first fraction!
We can now cancel these out.
Now our equation looks like this:
(1 / t+4) * (1 / t+4)
This can also be written as 1^2 / (t+4)^2 = 1 / (t+4) ^2
So the correct option is the third one.

4 inches = 1/3 foot
So the volume of that section is (150ft x 5ft x 1/3 ft) = 250 cubic feet
The whole trick to this question is knowing
how many cubic feet make 1 cubic yard.
1 yard = 3 ft
(1yd x 1 yd x 1yd) = 1 yd³
(3ft x 3ft x 3ft) = (3 ft)³ = (3)³ x (ft)³ = 27 ft³ <===
For the sidewalk project,
250 ft³ = (250 / 27) = 9.26 yard³ .
I think the way concrete contractors operate, they'll
want you to order and pay for 10 cubic yards.
