6. (x + 2)(3x - 1) - (x + 4)(x - 7)
i’m confused

Step-by-step explanation:

2x^2 +8x +26

Step-by-step explanation:

I think you're supposed to simplify this:

So what you do is: you must have learmt about FOIL

which means First, Outside, Inside, Last.

So, this is how to do it using FOIL:

(3x^2 -x+6x-2) - ( x^2-7x+4x-28)

Now simplify, combine like terms wherever you can,

(3x^2 +5x -2) - ( x^2 -3x -28)

Note: multiply the subtraction sign otherwise you will end up making a mistake,

3x^2 +5x -2 - x^2 +3x+28

3x^2 -x^2 +5x+3x-2+28

2x^2 +8x +26 Answer

Hope this helps!

Please mark brainliest if you think I helped! Would really appreciate!

Note: Some of these steps can be eliminated, i showed everything for the purpose of making things clear for you!

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
