|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!

HELP PLEASE WITH EXPLANATION
avanturin [10]
So hmm notice the picture below

that's the 30-60-90 rule, notice your triangle, the bottom-left-angle is a right angle, 90°, the angle atop is 30°, so the angle on the bottom-right has to be 60°, thus is a 30-60-90 triangle, and as you can see on the triangle on the left in the picture, those are the ratios for it

so 8 will be x, what is the longer leg or side in yours then? well, is \bf 8\sqrt{3}
