Answer:
6
Explanation:
Assuming that you mean a = -3 in your question....
|a + 3| + |a - 3|
If a = -3
|(-3 )+ 3| + |(-3) - 3| > here I just plugged in the given value of a<
Lets break this up.
Part 1) the FIRST absolute value
|(-3) + 3|
Lets just ignore the absolute value line for a moment here,
We have -3+3
This is 0.
So what is the absolute value of 0? It’s 0. Basically anything in those 2 lines || is an absolute value and it will come out as a positive number. For example,
|-7| is 7
Absolute value of -7 is 7.
Now lets go back to your RSM problem.
So far we have
0 + |(-3) - 3| or just |(-3) - 3|.
Part 2)
Simplify |(-3) - 3|
Again, ignore the | | for a moment.
What is -3-3? It’s -6.
Now what is the absolute value of -6? 6. So the answer is 6.
Hope this helped!
