Answer:
144x^2−y^2−169 because ther are no like terms
Step-by-step explanation:
Answer:
42*3=126
28*5=140
the GCD of 126=2*3*3*7
the GCD of 140=2*2*5*7
2*7
GCD=14
Step-by-step explanation:
Neither A nor B because there is repetition of X values
Given:
The length of field is n yards.
The length of a field in feet is a function f(n).
To find:
The function rule for this situation.
Solution:
We know that,
1 yard = 3 feet
Using this conversion, we get
n yard = 3n feet
The length of field is n yards. So, the length of the field is 3n feets.
The length of a field in feet is a function f(n). So,

Therefore, the required function rule for this situation is
.
Answer:

The solution set is 
Step-by-step explanation:
we have
