Answer:
2,300
Explanation:
This is given as:

Therefore, there are 2,300 ways that 3 persons can be selected from 25 people
Answer:
I think it's the third one sry if I'm wrong
50(30%) = 15
50 - 15 = 35
35 (6%) = 2.1
35 + 2.1 = $37.10
the total cost of his order is $37.10 !!
Answer:
Step-by-step explanation:
<u>Two ways to solve</u>
1.) Expand each term in the equation
- 7x = x · x · x · x · x · x · x
- 6x = x · x · x · x · x · x
- Count all the x’s ⇒ There are 13 x’s ⇒ 13x
2.) Add the coefficients
Hence,
Answer = 13x
So it's like 'which one of the number given is a factor of, say, 10' and the choices are 4,5,7,9. the answer is 5 so just factor out the equation
the factored out form is
factor out the 3x^2 and get
(3x^2)(3x^2-2x+1)
and 3x^2-2x+1 is the fourth choice
