Simplify the rational expression:<br> x^2+13x+42/x^2+15x+56
ANTONII [103]

Answer:

x+6/x+8

Step-by-step explanation:

First, factor out each of the expressions. You will use the AM method, where the last term is the factors multiplied together, and the middle term is the two added together. For the top, you would get (x+7) and (x+6) as your factors, and for the bottom you'd get (x+7) and (x+8). Based off of that, you can simplify your answer. The two (x+7)'s can cancel out, leaving you with a (x+6) over (x+8) as your answer.

nignag [31]

In this question, we're trying to find out how much Jamal spent on apples.

We know that he bought 2 pounds of red apples and 3.2 pounds of green apples.

We also know that each pound of apples, no matter what kind it is, are $1.65 a pound.

In order to find the total cost of these apples, we would need to multiply the amount of pounds he has to the cost per pound.

Solve:

2 · 1.65 = 3.3‬0

3.2 · 1.65 = 5.28‬

Add those numbers together:

5.28‬ + 3.30 =  8.58‬

This means that Jamal spent $8.58‬ on apples.

Answer:

$8.58‬
