Use the discriminant to describe the root of each equation 3x^2-10=0

Given a quadratic equation

The discriminant is defined as

In your case, the equation is defined by the coefficients

So, the discriminant is

The discriminant is involved in the solving formula as follows:

Which implies that:

In your case, since the discriminant is positive, you have two distinct solutions. Since 120 is not a perfect square, however, you will not get rid of the square root, so you will have two distinct irrational solutions.

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
