To solve this problem you must apply the proccedure shown below:
1. You have that Darren can get to work in

and <span>with the traffic and lights, he can average </span>

<span>.Therefore, you must apply the formula for calculate the distance, which is:
</span>

<span>
Where </span>

<span> is the speed and </span>

<span> is the time.
2. The time in hours is:
</span>

<span>
3. Substituying values, you have:
</span>

<span>
The answer is:</span>
Combine the like terms
(4x^2 + 2x^2) +(7x - 5x) + (3 - 8)
6x^2 2x -5
6x^2 + 2x - 5
Answer is A
<span>-0.00925 is the answer </span><span />
Important: Use the symbol "^" to denote exponentiation:
<span>x3 – 9x2 + 5x – 45 NO
</span><span>x^3 – 9x^2 + 5x – 45 YES
Look at the first 2 terms. They can be rewritten as x^2(x-9). Then look at the last 2 terms. They can be rewritten as 5(x-9). So, x-9 is the common factor here. Thus, the original expression becomes:
(x^2-5)(x-9).
Note that x^2-5 can be factored, so that the final 3 factors are:
(x-sqrt(5)), (x+sqrt(5)), (x-9).</span>
