(01.02 lc) simplify the following expression: 7x − 4y + 5z − 2x − 10y + z (5 points)

9x - 14y + 6z

All you have to do is add like terms so for example

2x and 7x are like terms

so are 4y and 10y

and 5z and z

I hope this helps :)!

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
