Which of the following represents the solution of the inequality 2x2 + 7x - 45 0? A {x|x € R, -4 B (-6,-4)u(,)
c {xlx € R, -4 5x5}
D
-5 -4 -3 -2 -1
0 1 2 3

30

Step-by-step explanation:

7! = 7*(2*3)*5*(2*2)*3*2*1 =

Ignoring the 7, there are 24 factors of this number as you will multily each of the factors of 6! by 7 to get each of the factors of 7! divisble by 7. But since you ignored the 7, you need to bring back the possible values of 7*6, 7*5, 7*4, 7*3, 7*2, 7*1.

24 + 6 = 30 divisors
