Explain how you can tell that the quadratic function y=x^+6x+15 has no real zeros without graphing the function

It's y intercept is positve 15 and has a positive slope and a positive "x^2" term

Lie

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
