Answer:
34
Step-by-step explanation:
trust me
First, put them directly above each other.
5a+2s=48
3a+2s=32
You need to combine these, but in order to do so, we want to get rid of one of the letters. The S's line up very well, and all we need to do is multiply the bottom equation by a negative 1. This will look like this,
-3a-2s=-32 (and add it to the other equation)
5a+2s=48
This gives you
2a=16
Divide both sides by 2 to get a by itself.
a=8, is your answer!
If it asked for s, you would put 8 into whichever equation seems easier for you, and then its just simple crunching it out.
Hope this helped!

Answer
Find out the what is the total distance Zohar needs to cut with the scissors .
To prove
As given
Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper.
As
Perimeter of the rectangle = 2(5x – 2) + 2(3x + 1)
As x = 4
Put in the above
Perimeter of the rectangle = 2 × (5 × 4 – 2) + 2 × (3 × 4 + 1)
= 2× (20 - 2) + 2 × (12 +1 )
= 2 × 18 + 2 × 13
= 36 + 26
= 62 units
Therefore total distance Zohar needs to cut with the scissors is 62 units.
