Step-by-step explanation:
-x+5+6x-7x-14
6x-8x+5-14
-2x-9
Answer:
Step-by-step explanation:
x² + 4x - 1 - x =x² + 4x -x - 1 { bring the like terms together and add}
= x² + 3x - 1
Let the third side = x.
The sum of any two sides must be greater than the third side
14 + 9 > x
23 > x
14 + x > 9
x > -5
9 + x > 14
x > 5
So 5 < x < 23
Answer:

Step-by-step explanation:
FH is the combined lengths of FG and GH.
In an equation, this is:

We already know that FG is 8 and that GH is 14. Thus:

Add:

So, the length of FH is 22.
And we're done!
