3|x + 7| = 21

PLEASE HELP ASAP

x=0, x = -14

Step-by-step explanation:

You can first divide each side with 3, which will result in :

|x+7| = 7

Then there is two cases where x is positive and x is negative :

x+7 = 7

and

x+7 = -7

x = 0

x = -14

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
