Answer:
The multiplicative Inverse of any number except zero, is 1 over the number
Step-by-step explanation:
The ratio 1: 3 means there is 1 red one and 3 blue ones.
For the ratio 3:1 there needs to be 3 red for every one blue.
You have 3 blue ones, so you would need 3 x 3 = 9 red ones.
You already have 1 red one so you would need 8 more.

The answer is x squared -21x -18.
X^2-21x-18
My work is in the picture below
Answer:
The answer is -4.
Step-by-step explanation:
Since its f/g, we know that f(n)= 2n^2+2n and g(n)=n+1.
N= -2. You will plug in all the values of n = - 2.
So...
2n^1+2n/n+1
2(-2)^2+2(-2)/-2-1 which will give you -4.
