A
Step-by-step explanation:
Answer:
The greatest number of displays that can be built using all the boxes are 
(Using
blue boxes and
yellow boxes for each display).
Step-by-step explanation:
In order to answer the question, the first step is to divide the number of blue boxes and yellow boxes and look for a common ratio ⇒

This means that we have a ratio
for blue boxes and yellow boxes.
We find that each display will have 5 blue boxes and 7 yellow boxes.
To find the greatest number of displays that can be built we can do the following calculation

Or

(We can divide the number of blue boxes by its correspond ratio number or the number of yellow boxes by its correspond ratio number)
In each cases the result is 13 displays.
The answer is 13 identical displays
2x + 5 - 6x + 21 = 2(3x - 5) - 4
distribute
2x+5 -6x +21 = 6x-10 -4
combine like terms
-4x +26 = 6x -14
add 4x to each side
26 = 10x -14
add 14 to each side
40 = 10x
divide by 10
4 =x
Answer: A. - 2.215
Step-by-step explanation:
• A residual is the difference between the actual value and the predicted value in a regression model. It represents the vertical distance from the actual point to the point on the regression line.
Hence, the residual in this case = -2.215
Answer:
d or 4x²-12x-9
Step-by-step explanation:
factoring d you get (2x-3)²
which is a perfect square trinomial so
d or 4x²-12x-9
