I have the problem written out (in the picture below) but tell me if it is unclear and I will better explain it to you!
3y + y = 4y
3y = y + y + y
y + y + y + y = 4y
hope this helps
The side length of the new square would be 9. When you dialate you multiply by the square factor, so 1/2 times 18 equals 9.
Ok
You look at how many ‘x’ there are then you add them together 6x+3x+x+10+40=180
I think you can take it from here?
The only factors that equal 62 are
62 • 1 = 62
and
31 • 2 = 62.
Hope this helps!
