|x+5|+20=4 Needs to show work on how you came up with the answer.
arlik [135]

Answer:

No solution

Step-by-step explanation:

So we have the equation:

|x+5|+20=4

First, subtract 20 from both sides:

|x+5|=-16

Now, we can stop. Recall that absolute value will always <em>always</em> give a positive answer.

Since this equals -16, this means that there is no solution.

And we're done!

4x6.2= 4(6+0.2) = (4x ) + (4 x )
PSYCHO15rus [73]

Answer:

X=3.1

(4•3.1)+(4•3.1)

Step-by-step explanation:

4 of 6.2 is equal to 24.8

4•(6+0.2) = 24.8

4•3.1=12.4•2=24.8

12.4+12.4=24.8

(4x)+(4×)=24.8
