So first what you are going to do is divide synthetically your root aka factor into your given equation. Then you are going to kind of guess ands check to find the other factor by synthetically dividing what you have left which should be
x^2 +2x +1 by -5, 5 (to make sure there is no multiplicity), 1, and -1 until you get zero in your remainder spot. The number you used to divide will be your other root.

Christine runs 10 miles in 75 minutes. At the same rate, how many miles would she ru I miles

Len [333]

Answer:

$\frac{46}{5}$ miles [or, 9.2 miles]

Step-by-step explanation:

Complete Question:

Christine runs 10 miles in 75 minutes. At the same rate, how many miles would she ru n in 69 minutes?

Solution:

We need to find the unit rate first and then find our answer. To get unit rate, we need to know the number of miles she runs in "1 minute". So, we will divide number of miles by number of minutes, that is given. Hence:

$\frac{10}{75}=\frac{2}{15}$

That means in 1 minute, Christine runs 2/15th of a mile.

Now, we want to know how many miles she will run in 69 minutes. We simply multiply unit rate (2/15) by the number of minutes (which is 69). Thus we have:

$\frac{2}{15}*69=\frac{2*23}{5}=\frac{46}{5}$
