Answer the attached question by selecting of the the given answers.

For this case we must simplify the following expression:

So, by rewriting we have:

We factor the parenthesis trinomial by looking for two numbers that, when multiplied, are obtained -3 and when added together, -2 is obtained. These numbers are -3 and 1, so:

On the other hand we have to:

Last we have:

Thus, rewriting the expression:

Simplifying:

Option A

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
