Add the Polynomials (2 + 2k3 + 7k4) + (4k4 – 2 – 7k3)
O 1154 – 563
O 1164 +263 + 8
O 1154 + 2k3 + 1
O 11k4 + 2k3

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

How many groups are there?

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