Ineed some to find the equations for the questions. asap.

5) Lets use x for the unknown middle side. Since all the sides have to equal to perimeter, we can set everything equal 43.

(x-3)+x+(2x-2)=43

That would be your equation.

6) Knowing what we know from the previous problem, we can set the equation to 27.

(x-3)+x+4(x-3)=27 (we can plug in x-3 to represent the first side)

7) Since all the sides have to equal to perimeter, we can set everything equal 25.

a=2b-2

c=b+3

(2b-2)+b+(b+3)=25

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
