1. subtract & simplify (–y2 – 4y – 8) – (–4y2 – 6y + 3)

2.multiply and simplify 2x2y3z2 · 4xy4x2

3.multiply and simplify (x – 4) (x2 – 5x – 6)

can someone and show how you got your answer

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:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
