Answer:
Is it 2160?
Step-by-step explanation:
This is permutation
Imagine □□□□□, each □ represents a digit
For the 1st □, there are 6 choices, since "0" cannot be the first digit, or else it is not a 5-digit number
For the 2nd □, there are 6 choices (1 out of the 7 number is already used)
For the 3rd □, there are 5 choices (2 out of 7 numbers are used)
And so on.....
Therefore,
6×6×5×4×3 = 2160

Answer:
D) -30x^2 -64x -18
Step-by-step explanation:
Given:
f(x) = 6x +2 and g(x) = -5x - 9
f(x).g(x) = (6x + 2) (-5x - 9)
Use distributive property
= 6x(-5x -9) + 2(-5x - 9)
= -30x^2 - 54x - 10x -18
= -30x^2 -64x - 18
Answer: d) -30x^2 -64x -18
Thank you.
