Question

If the length of FH is 18 units, what is the value of x?

Answer 1

Well if FG is 4x and GH is 2x the you add them to get 6x for FH. Solve for x so 6x=18 which means x=3. Hope this helps

Answer 2

we know that

`FH=FG+GH`

In this problem we have

`FH=18\ units\\FG=4x\\GH=2x`

substitute in the formula above

`18=4x+2x`

solve for x

`6x=18`

`x=18/6`

`x=3\ units`

therefore

the answer is

The value of x is
`3\ units`
