Answer:
36x^2 + 24x + 4
Explanation:
The perfect square has the following general formula:
(a + b)^2 = a^2 + 2ab + b^2
Now, we will expand the given perfect square based on the above general formula:
(6x + 2)^2 = (6x)^2 + 2(6x*2) + (2)^2
= 36x^2 + 24x + 4
Hope this helps :)
Answer:
f(5) = -2
Step-by-step explanation:
You look on the x-axis for 5 because f(5) means let x = 5. Then go down to the graph (the red zig-zaggy line) At the red line (you're still directly under the 5) look over to the y-axis to find the value. That's your answer. It is -2. The point (5, -2) is on the red graph.
f(5) = -2
So, to figure out this problem you first need to solve for how much you have left after paying the base fee. Take the total ($84) and subtract by the base fee ($27). You will get 57 as your answer. Then, take $57 and divide it by $0.15 to get your answer. It is 380 minutes each month. The equation here is 84=27+0.15x.
