Use the discriminant to describe the roots of each equation. then select the best description. 2x2 + 7x + 6 = 0 double root real and rational roots real and irrational roots non-real roots

So the equation to find the discriminant is √(b^2 - 4ac), with a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation above, we can solve for it as such:

Since the discriminant is greater than zero and a perfect square, this means that there are 2 real, rational solutions to this polynomial.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
