Answer:
12
Step-by-step explanation:
3x^2
because the information provided states that x = -2, that is what we are going to replace x with.
3(-2)^2
the next step is to evaluate the power because that is next in PEMDAS.
(-2)^2 = 4
that leaves us with:
3 * 4 = 12 ( the " * " represents the multiplication sign)
hope this helps!
To find the mean you add up all the numbers then divide the sum by how many numbers there are :
8+16+12+11+8=55
there are 5 numbers in the equation so you divide 55 by 5 :
55÷5= 11
the mean is 11
hope this helped

Answer:
The answer is D. water fountain.
Step-by-step explanation:
If you look at the graph for the point (-2.5, 3.0), you need to find -2.5 on the x-axis and 3 on the y-axis. The "Water Fountain" point is past negative two but not quite at 3 yet; it's in between. Then you go up three times. Even though the graph is going by 2's, the point is located exactly in between 2 and 4, which is 3. Hope this helps!
