Question

HELP! How would I find the perimeter of a figure with the 4 sides that are
x-3
2x+8
2x+5
x+6

Answer 1

The perimeter is the sum of the lengths of, in this case, the four sides.

P = x-3 + 2x + 8 + 2x + 5 + x + 6

Simplify that sum. Post what you get and we can compare answers, okay? @Brookebrookiee

Answer 2

So I would just add those together?

Answer 3

Yes, add the like terms together. Attached is a reminder about how to recognize like terms.

Answer 4

4x+16?

Answer 5

I got the 16 but not the 4x. Check the sum of your x terms.

Answer 6

2x?

Answer 7

No. Look at the x terms: x + 2x + 2x + x

What is the sum? Count x as" one x"

Answer 8

6x?

Answer 9

Yes. So, the perimeter = 6x + 16
