Answer:
x+5 is the factor..
Step-by-step explanation:
xsquare + (8+5)x + 40
or, xsquare +8x+5x+40
or, x(x+8)+5(x+8)
(x+5)(x+8)
5.5 hours. 5 hours and 30 minutes
The total pages she wants to finish (360) minus the pages she has read (112.5) equals to 247.5
Then divide it by the 45 (the rate of pages she reads per hour)
5.5 hours.
Answer: {0, 5, 7}
Step-by-step explanation:
{0, 5, 7}
There are 8 proper fractions with a denominator of 30 that are irreducible:
1/30, 7/30, 11/30, 13/30, 17/30, 19/30, 23/30, 29/30
We cannot count any even numerators, as 30 is even and would therefore make the fraction reducible.
We cannot count any numerators that are a multiple of 3, as it is a factor of 30. Likewise we cannot count any numerators that are a multiple of 5.
