Factor using the GCF and Distributive Property. 12x - 40
charle [14.2K]

Answer:

4(3x - 10)

Step-by-step explanation:

Both terms of the original are divisible by 4. Once we factor it out, divide the original terms by 4 to find what to put in the parentheses.

12x ÷4 = 3x

-40 ÷4 = -10 Put 3x -10 in parentheses

4(3x – 10)

From the 11
elena55 [62]
Selecting r objects out of n objects, can be done in C(n, r) many ways.

For example selecting groups of 4 people out of 10 people can be done in
C(10, 4) many ways.


C(n, r) is calculated as follows: C(n, r)= \frac{n!}{r!(n-r!)}, 

where n! is 1*2*3*...*(n-1)*n


3 men out of 11 men, and 2 women out of 6 women are to be selected.

This can be done in C(11, 3) and C(6,2) ways respectively.

Since any of the selected men group can be combined with any of the selected women group, there are C(11, 3)*C(6,2) many ways of selecting the team of 5.


C(11, 3)*C(6,2) = \frac{11!}{8!3!} * \frac{6!}{4!2!}= \frac{11*10*9*8!}{8!*3!}* \frac{6*5*4!}{4!*2!}= \frac{11*10*9}{3*2*1} * \frac{6*5}{2*1}=

165*15=2475
