Answer:
B. 
Step-by-step explanation:
The given quadratic trinomial is;
Comparing this to 
, we have a=5,b=17,c=6.
Two factors of 30 that add up to 17 is 15 and 2.
We split the middle term to obtain;
We factor by grouping;
Factor further
The correct answer is B.
Answer:
Step-by-step explanation:

Determine the coordinates of the centroid
Represent the coordinates with C.
C is calculated as follows:
Substitute values of x and y in the given equation
<em>The above is the coordinate of the centroid</em>
Answer: -9.1
Explanation
-3x +12.4=39.7
First minus 12.4 from both sides
-3x +12.4=39.7
-12.4 -12.4
-3x=27.3
Now devid both sides by -3
X= -9.1
Y=-3x+36 because the line crosses the y axis at 36
