Answer: The age of the twins is 10 years.
Step-by-step explanation:
Suppose the age of older sister be x
Let the age of twins sister be x-9, as they are born after 9 years.
Product of their ages be
Sum of their ages will be
According to question,
So, Age of older sister will be 19 years.
Age of the twins will be
Hence, the age of the twins is 10 years.
Well you could divide 120 into 20 and get 6 so the length and width could be 20 as one and 6 as the other
Collected at twice the amount collected each time the previous time
Answer:
The composite function;
f(g(x) = 2x^2 + 15
Step-by-step explanation:
Given f(x) = 2x + 1 and g(x) = x^2 + 7 ;
we want to find f(g(x))
This is simply a composite function which involves fixing the function g(x) into f(x)
Thus, we have
f(g(x)) = 2(x^2 + 7) + 1
f(g(x)) = 2x^2 + 14 + 1
f(g(x)) = 2x^2 + 15
