Answer:
1st multiply g and f then h
The answer is 0.9
Because the scatter plot is a positive liner relationship the answer would have to be positive but the liner relationship is not perfect so the value would not be 1.
Answer: a = -3
Explanations:
The given equation is:

This can be re-written as:

Collect like terms:

Cross multiply:

To verify if the solution is correct, substitute a = -3 into the question given. If the Right Hand Side equals the Left Hand Side, then the solution is correct.

Since the Left Hand Side = Right Hand Side = 7, the solution a = -3 is correct
The answer to your problem (or what i got) was 34u^2(34units squared)
A and D because x is 1/3y not 3y and x times y would be 48 and yes I'm sure
