Answer:
24
Step-by-step explanation:
The question is saying, how many three digit numbers can be made from the digits 3, 4, 6, and 7 but there can't be two of the same digit in them. For example 346 fits the requirements, but 776 doesn't, because it has two 7s.
Okay, on to the problem:
We can do one digit at a time.
First digit:
There are 4 digits that we can choose from. (3, 4, 6, and 7)
Second digit:
No matter which digit we chose for the first digit, there is only going to be 3 of them left, because we already chose one, and you can't repeat that same digit. So there are 3 options.
Third digit:
Using the same logic, there are only 2 options left.
We have 4 choices for the first digit, 3 choices for the second, and 2 for the third.
Hence, this is 4 * 3 * 2 = 24 three-digit numbers that can be made.
Answer:
5/2-7/2 i or 2.5-3.5i
Step-by-step explanation:
expand the fraction remove the parenthesis and then calculate
Answer:
The correct option is c.
Step-by-step explanation:
The quotient of the polynomials is

We need to find the remainder by using long division method.
The dividend of the given expression is


The long division method is shown below.

From the below attachment it is clear that the quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend.
Therefore the correct option is c.
So it’s $15 per month so that is what you are gonna multiply by x. You start out with $75 so that’s the initial fee. 15x + 75 is your expression.
