Answer:

180 in

Step-by-step explanation:

The perimeter is just the sum of the lengths of the sides of the shape.

So all we need to do here is:

40+10+(40-18)+(50-10)+18+50.

I got (40-18) for the bottom of the top rectangle, the part that is poking out.

I got (50-10) for the right side of the rectangle that is poking out towards the bottom.

40+10+(40-18)+(50-10)+18+50

40+10+22       +40       +18+50

50     +62                      +68

50+62+68

112+68

180

180 in

I'm going to post a drawing here to show the lengths I was talking about:

Which of these is a simplified form of the equation 8y + 4 = 6 + 2y + 1y?
larisa86 [58]
The first one would be the right one!
  
you just take all the y one side and the numbers on one side 
 so 8y+4= 6+3y

now 8y-3y= 6-4

therefore 5y = 2
