Question

Helppppp it’s an emergency!!!!!

Answer 1

Answer:

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

$x = 12.125$m

$AB = 20.125$m

$EF=31.375$m

Step-by-step 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 :)
