I need a answer quick
Consider the polynomial p(x) = 16x4 - 81y4. Which of the following are equivalent expressions?
Select all that apply.
(4x2 - 9y2)(4x2 - 9y2)
(4x2 – 9y2)(4x2 +9y2)
(4x2 +9y2)(2x - 3y)(2x – 3y)
(4x2 +9y2)(2x + 3y)(2x + 3y)
(4x2 +9y2)(2x + 3y)(2x – 3y)

Is the third one of the answer

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
