Answer:
UW=14
Step-by-step explanation:
First we know that UV+VW=UW, so:
4+x+10=2x+14
Solve for x first:
x+10=2x+10
10=x+10
x=0
Then, substitute the X
2(0+14)=14=UW
To check your answer, substitute and add UV and VW
4+(0)+10
14

<span>-10 < x - 9
</span><span>-10+9 < x - 9+9
-1<x, or
x> - 1</span>
Step-by-step explanation:
The magnitude of x is equal or less than 7.
=> We have |x| <= 7.
