C and D are true. To solve, just factor out the common terms by dividing the polynomial. A would be 3m(5m^2-2) and is wrong as the 6m was not divided by 3m. B would be 6m(m+3) and is wrong as you can only factor out one m as they only share one m.
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

Answer:
Try useing a therom.
Step-by-step explanation:
27:In the first question you could use SAS which means side angle side because D is the midpoint and it tells you that ab and bc are equal.
Same for 28
