The curve y= (k+2)x^2 meets the line y=(k+3)x +3. find the range of possible values of k.
could somebody explain how they get to their answer, too?
skills: simultaneous equations, discriminant, quadratic inequality & rearranging quadratics

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

step-by-step explanation:

you need to give us more information since we can't answer
