All 3 sides are equal in an equilateral triangle...

2x - 5 = 3x - 22
-5 + 22 = 3x - 2x
17 = x

2x - 5 = 2(17) - 5 = 34 - 5 = 29
3x - 22 = 3(17) - 22 = 51 - 22 = 29
x + 12 = 17 + 12 = 29

as u can see, all sides measure 29 inches

Answer:

29 inches.

Step-by-step explanation:

Given that, the three sides of an equilateral triangle are [tex](x + 12), (2x - 5),(3x - 22)[/tex]

As we know that, the sides of an equilateral triangle are of same length.

So,

[tex]\Rightarrow x + 12=2x - 5[/tex]

[tex]\Rightarrow 2x - x=12+5[/tex]

[tex]\Rightarrow x=17[/tex]

Putting the value of x in each expressions,

[tex]x + 12=17+12=29[/tex]

[tex]2x -5=34-5=29[/tex]

[tex]3x -22=51-22=29[/tex]

So the side length is 29 inches.
