F(x) = x2 - 4x - 21.

Find the area of the triangle formed by the origin and the points of intersection of parabolas y=−3x^2+20 and y=x^2−16.

The measures of the legs of a right triangle are 15m and 20m . what is the length of the hypotenuse

In dire need~! describe how to use area models to find the quotient 2/3 divided by 1/5. check your work by also finding the quotient 2/3 divided by 1/5 using numerical operations only.
