Determine the answer to -3 + (-5) and explain the steps using a number line

-8

Step-by-step explanation:

-3+(-5)

When we solve the above the question we will get the answer which is equal to -8.

We have to sole the above equation by the number line

A number line consist of the negative number on the left hand side and positive numbers on right hand side which are separated by zero at equal distance .

-3+(-5)

On the number line we have to start from zero , then we have to go back 3 steps that is on the left hand side of the number line .

Now , again we have to 5 back steps on a number line  and we get the our answer which is equal to -8.

Hence , the correct answer is -8.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
