Using the identity
,

You got 21 papers on Monday. Because if you add 3 7 times it equals 21.
Hope it is correct!
I might be wrong but it might be 62
3x^2 = 7x - 3
3x^2 - 7x = -3
x^2 - 7/3x = -1
x^2 - 7/3x + 49/36 = -1 + 49/36 = 13/36
(x - 7/6)^2 = 13/36
x - 7/6 = + or - sqrt(13)/6
x = 7/6 + or - sqrt(13)/6
x = (7 + or - sqrt(13))/6
Answer:
Your answer is 46 minutes.
Step-by-step explanation: By doing the median of the numbers you order the pairs from least to greatest. 38, 45, 47, 52. You find the middle number if its an even number of pairs you pick the two middle most numbers and add them together.
45 + 47= 92
Then you divide the sum by the number of pairs. Which we have 2 pairs.
92/2 = 46 hence your answer will be 46 minutes.
