ILL GIVE BRAINLIEST AND 10 POINTS

Step-by-step explanation:

This is a quadratic in disguise. To visualize this better, let . We have:

To factor, we can write out the format . We're looking for numbers , , , and such that the following is true:

We find the following numbers:

Thus, we have:

Substitute back to get your final

Equation  -8 ≤ 3n+4 ≤ 10

Solution -4 ≤ n ≤ 2

Step-by-step explanation:

sum of 3 times a number and 4

3n+4

is no more than 10  

3n+4 ≤ 10

and no less than -8

-8 ≤ 3n+4 ≤ 10

To solve

Subtract 4 from all sides

-8-4 ≤ 3n+4-4 ≤ 10-4

-12 ≤ 3n ≤ 6

Divide all sides by 3

-12/3 ≤ 3n/3 ≤ 6/3

-4 ≤ n ≤ 2
