can be changed into this equation:

The 32 and 8 have a common factor of 8 and can be simplified to become this equation:

Now multiply across to get

which then simplifies to

which as a decimal is 41.333 (repeating 3s). Nearest whole number is 41.
Your answer is
41
B. (k+10f)(k-5f) you can tell in 2 ways. 1. if the second sign is neg then the signs in the factors are going to be one neg and one positive so that knocks out C and D. Then you look at the second term and since the 5 is positive then the 10 has to be positive so you end up with a positive 5kf.
The second way is to FOIL them out. When you check B you get

combine your like terms and you have your original expression of

Hope that helps
Answer:
k=6
Step-by-step explanation:
Line partition formula
1/b(x2-x1)+x1, 1/b(y2-y1)+y1
Where b is the number partitions.
We know the x values so Subsitue 17 for x2 and 2 for x1. and we know this value must equal 7.
1/b(17-2)+2=7
1/b(15)=5
1/b=1/3
b=3
so the partition is 1/3

So let find the y coordinate

So our y coordinate is 6.
Answer:
13.2 or 13 1/5 inches
Step-by-step explanation:
2 1/5 in/day * 6 days = 13.2 or 13 1/5 inches
OR
2 1/5 in
+ 2 1/5 in
+ 2 1/5 in
+ 2 1/5 in
+ 2 1/5 in
+ 2 1/5 in
------------
13 1/5 in
