(x + 2y) ^2
(x + 2y) (x + 2y)
x^2 + 2xy + 2xy + 4y^2
= x^2 + 4xy + 4y^2
Answer:
it's a not c
Step-by-step explanation:
i just got it right on usa test prep
4/7 is 28/49 in simplest form.<span />
The correlation coefficient for the data in the table is A. –0.993
<h3>Calculations and Parameters:</h3>
Using this formula: 
We would use x and y to represent the unknowns.
n = 4
We have,
- ∑x = 42,
- ∑y = 44.37 ,
- ∑xy = 461.3
- ∑x^2 = 446,
- ∑y^2 = 494
Putting these values in the formula
would bring the answer as. A. –0.993
