9 because 16 plus 9 is 25 and 21 plus 9 is 30. now you have 25/30
Now you have to simplify:
25 divided 5 is 5 and 30 divided 5 is 6. So 5/6
The equation of any line is:

m is slope.
We just need to put inside of equation x=(-3) and y=5:


It follows that equation of a line is:
Answer:
27
Step-by-step explanation:
4 times 4 is 16
2 boxes in the middle
4 tiny boxes in each one in the middle
1 entire one on the outside
1+4+4+2+16= 27
First you plug in the data to the formula. So it will be 2(1/3+1/2). You then want to add the fractions together but must first find the common denominator which will be 6. So it is 2(2/6+3/6). The fractions then add up to be 5/6. So all you have to do is multiply it by 2 to get 5/3 which simplifies to 1 2/3 so it is D.
