Answer:
sister = 6 years
John=18 years
Step-by-step explanation:
A(S) + 12 = 3 * A(S), subtracting A(S) from both sides one gets 12 = 2 * A(S). Now dividing both sides by 2 we get A(S) = 12/2 = 6 . Therefore, the age of the sister is 6 years when her brother John is three times as old, that is 18 years.
ANSWER

EXPLANATION
The given binomial expansion is:

Compare this to

we have a=2x , b=-3y and n=10
We want to find the coefficient of the term

This implies that, r=5.
The terms in the expansion can be obtained using

We substitute the given values to obtain;



Hence the coefficient is;

The answer should be C :) in order for there to be a function, first rule is the x number cannot repeat

Answer:
I don't know if this is correct but id say
