Answer 6

alright well lets work this out. area is b*h (base * height) correct or Length * width as in this example

Answer 7

we know width is 2x+1

Answer 8

yes

Answer 9

and the length is 3 less than 3 times the width. so if you write that out it looks like this 3(2x+1)-3

Answer 10

simplify that for me so I know you're paying attention lol

Answer 11

6x + 3 - 3

Answer 12

im sorry I meant twice as long not 3 times my fault so 2(2x+1)-3

Answer 13

4x + 2 - 3

Answer 14

simplify it further. what's 2-3

Answer 15

4x + -1

Answer 16

right which is basically 4x-1

Answer 17

true

Answer 18

so now you have width=2x+1 and length=4x-1. now how does that other formula go again? L*W

Answer 19

8x

Answer 20

(2x+1)(4x-1) multiply them Cello
