Answer:
42 ft
Step-by-step explanation:
18 plus 24 equals 42 feet
6 x 2 + 4 x 3 = 12 + 12 = 24
Lets discern the infomation:
number_men = 165*0.6 = 99
so there are 99 men
non_fiction = 165 * 0.4 = 66
so 66 authors write non-fiction.
men writing non-fiction are 40, so 59 men write fiction, and 26 women write non-fiction.
probability of author non-fiction or man?
non-fiction: 40 men + 26 women = 66 total
man writers = 99
so in total 99 man + 26 women = 115 authors
hence the probability is:
115/165 = 69.6%
The Last on = 45x^2 - 2x - 8
Reason being is because you would group and multiple:
(9x - 4) • (5x +2)
I hope this helps you
f(8)=2.8+5=21
g(8)=3.8+6=30
f-g(8)=21-30= -9
