Y = 2x^2 + 4x - 17 from quadratic function to vertex form

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

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)
