Answer:
36
Step-by-step explanation:
x^2 + 12 x = 40
To complete the square, take the coefficient of the x term
12
Divide by 2
12/2 = 6
Square it
6^2 = 36
Add 36 to each side
Answer:
infinite solutions
Step-by-step explanation:
-9(x+3) +12 = -3(2x+5)-3x
Distribute
-9x-27 +12 = -6x-15-3x
Combine like terms
-9x -15 = -9x-15
Add 9x to each side
-9x-15+9x = -9x-15+9x
-15 = -15
This is a true statement so it is true for all x
18 - 2H = 12 - .5H
Combine the variables
18 - 2H + .5H = 12 - .5H + .5H
18 - 1.5H = 12
Combine the whole numbers
18 - 18 - 1.5H = 12 - 18
-1.5H = -6
Divide by -1.5
-1.5H/-1.5 = -6 / -1.5
H = 4
The answer is 4 hours
The correct answer is: " 48:32 " .
__________________________________________Explanation:
__________________________________(3*80) divided by (3+2) = 240 ÷ 5 = 48 ;
__________________________________ (2*80) divided by (3+2) = 160 ÷ 5 = 32 ;

Answer:
D.) Median for both bakeries because the data is not symmetric
Step-by-step explanation:
You can compare box-and-whisker plots for the two bakeries
.
Neither bakery has a normal distribution.
The median for Bakery A is not in the middle of the box.
Rather, it cuts the box into two unequal parts, so the data does not have a normal distribution.
The longer part is below the median, so the data are skewed to the bottom.
Similarly, the data for Bakery B are skewed to the top.
The values in the tails pull the mean down for Bakery A and up for Bakery B, so it is better to describe the centres of distribution in terms of the medians.
