Answer: the perimeter is 108 yards. Here are the steps:
A:B
4:9 (Ratio of side A to side B.)
12:27 (A was increased 3x, so B needs to be increased 3x to keep above ratio the same when simplified. Ex. 15:20 simplifies down to 3:4.)
27+27+27+27=108yds (Perimeter is all of the sides added up.)

<span>because 720 multiplied by 1.25 equals 906.25</span>
Number of periods to double = 72/interest rate %
<span>72/0.43* = 166.15 months = 13.85 years. </span>
Step-by-step explanation:
The third option: 5x(x^2+3)(4x-5)
because FOIL first, inner, outter, last
The two parentheses become (4x^3-5x^2+12x)
then 5x outside multiplys that whole parentheses. To get your correct expression
