Question

Helppppp it’s an emergency!!!!!

Answer 1

Equation:
`2(x+8)+2(3x-5)+23 = 126`

`x = 12.125`m

`AB = 20.125`m

`EF=31.375`m

Explanation:

The equation of the perimeter of this shape can be written as:
`2(x+8)+2(3x-5)+23 = 126` (Sides with the same number of dashes are equal in length)

Which becomes:

`2x+16+6x-10+23=126`

`8x+29=126`

`8x=97`

`x= 12.125`

Since AB =
`x+8`, we can substitute to get the length of AB:

`x+8 = 12.125+8`

`=20.125`

We can also use substitution to solve for the length of EF:

`3x-5=3(12.125)-5`

`=31.375`

Hope this helps :)
