Simplify each expression, and then arrange them in increasing order based on the coefficient of n. -5(n3 - 12 - 1) + n(n2 = n)
(n2 - 1)(n + 2) – n2(n-3)
nền - 4) + 5n3 - 6
1
2n(n2 - 2n – 1) + 3n2
1

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

It is 6% because if you subtract 69-58=6 so 6% is the answer to your question.
