Answer:

2 units

Step-by-step explanation:

ok, so, the line below says HJ is (x+1) units long. therefore:

2x-16+8 = x+1

now, let's isolate the variable.

2x-x = 1+16-8

x = 9

since we now defined variable x, we can add it to the equation that determines the length of HI.

2x-16

2(9)-16

18-16

2

the length of line segment HI is 2 units

hope this helped!

HI + IJ = HJ

With this knowledge you can from an equation like so...

2x - 16 + 8 = x + 1

Now combine like terms and solve for x

2x + (- 8 + 8) = x + 1 + 8

2x = x + 9

2x - x = x - x + 9

x = 9

To find HI plug 9 in for x and simplify

2(9) - 16

18 - 16

2

The length of HI is 2!!!

Hope this helped!
