The area of a rectangle is L x W, so 9(5+x) is the formula for the area in factored form. It can be simplified to 45+9x
Assuming it’s a regular polygon :225
either $0.50 × $1 or $0.50÷ $1 hope this answer helps
The answer is 22. Work: n=3 and 3 to the second power would be 9 because 3x3=9 and 9+13=22. Hope I could help! Tell me if i’m wrong though!
