Answer:
Step-by-step explanation:
because 
is 11-4, which is 7. And you don't change the x.
Answer:
x = 4
Step-by-step explanation:
12/15=28/a which is a=35
then 35+28=63
14x+7=63 and x would be 4
Since area is length times width it will be 3 because it is a sqaure
Answer:
Step-by-step explanation:
We can tell that this absolute value function opens up, so the vertex will be at the x value where the output is the lowest. The lowest you can make |x+5| go is 0, because everything else will be a positive number is greater. The one x value that does that is -5. Plug in -5, and you will get |-5+5|-1=-1. So, the ordered pair for the vertex will be (-5,-1)
