I believe it'd be -x - 18 you'd add the 12x and 2x and get 14x-15x and get -x then you'd combine the -15 and -3 to get -18.
Answer:

The domain for x is all real numbers greater than zero and less than 5 com
Step-by-step explanation:
<em><u>The question is</u></em>
What is the volume of the open top box as a function of the side length x in cm of the square cutouts?
see the attached figure to better understand the problem
Let
x -----> the side length in cm of the square cutouts
we know that
The volume of the open top box is

we have



substitute

Find the domain for x
we know that

so
The domain is the interval (0,5)
The domain is all real numbers greater than zero and less than 5 cm
therefore
The volume of the open top box as a function of the side length x in cm of the square cutouts is

0.2 = 2/10 = 1/5 but 0.02 = 2/100 = 1/50 so 1/5 > 1/50 :D
Answer:
x≤−9
Step-by-step explanation:
x+5≤−4
-4-5=-9
you subtract 5 form each side
therefore x≤−9
hope this helps
