Can someone please help me with this maybe get a better understanding if you have the time to tell me?

Colt1911 [192]

Step-by-step explanation:

Absolute value function:

|x| = x when x >= 0.
|x| = -x when x < 0.

Swim 3 feet under water => |-3|

Stand 20 feet above => |20|

Using the absolute value function,

we have |-3| = 3 and |20| = 20.

Since 3 is less than 20, |-3| < |20|. (C)

Find FH <br> Need help ASAP !!

otez555 [7]

Answer:

$FH=22$

Step-by-step explanation:

FH is the combined lengths of FG and GH.

In an equation, this is:

$FH=FG+GH$

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

$FH=8+14$

Add:

$FH=22$

So, the length of FH is 22.

And we're done!
