2x + 2x + 32 = 256

-32

2x+2x = 224

4x=224

/4

x= 56





lenght = width+16

perimeter = width + width + (width + 16) + (width + 16)

perimeter = x + x + (x+16) + (x+16)

perimeter = 2x + 2((x+16)



therefore width = 56 
length = 72

95 divided into 4524
nignag [31]
I hope you mean 4524 divided by 95. That would look like this:4524/95. In that case, your answer would be a long decimal but rounded it would be: 47.62
If you mean 95/4524, then your answer would be: 0.00994

JulijaS [17]

Hey there!

Think of 45000 being split to 9 pieces.

Each piece would be 5000 dollars.

Thus, the ratio would be 20000 to 25000

Hope this helps :)
