Step-by-step explanation:
(10x² - 10x - 6) + (x + 6)
10x² - 10x - 6 + x + 6
10x² - 9x - 6 + 6
10x² - 9x

Answer: B: 41, C: 68, D: 71.
Step-by-step explanation: A triangle's angles have to add up to 180 degrees for it to be considered a triangle. If you were to add up 71, 41, and 68, then it would equal 180 degrees. This means that out of all the other measurements, these are the three possible angle measures that can be used to make a triangle.
(I figured this out by taking 3 random sides from the list there and adding them up to see if they equal 180.)
In mathematics, the irrational numbers are all the real numbers which are not rational numbers, the latter being the numbers constructed from ratios of integers.
Notice that the denominators are 3 and 7, which are factors of 21.
So express all the fractions with denominator 21:
On Monday

are sold
On Tuesday

are sold
On Wednesday

are sold
by Thursday

of the tickets was sold.
