Answer:
The expression is not completely factored.
Step-by-step explanation:
The expression of
can be broken up into two binomials:
![[x - 2][x + 2]](https://tex.z-dn.net/?f=%5Bx%20-%202%5D%5Bx%20%2B%202%5D)
Together, you have this:
![3[x - 2][x + 2]](https://tex.z-dn.net/?f=3%5Bx%20-%202%5D%5Bx%20%2B%202%5D)
** There is alot of missing information to this question, but at least you know how to work this out.
I am joyous to assist you anytime.
Answer: So our equation is 
Laura does:

while Sean does:

So sean sums four times the number 2/3, while Laura sums two times the number 4/3, this is because we are working with a multiplication, and the order of the factors does not alter the product.
The two are splitting the equations in different ways.
Answer:
18.7 m/h
Step-by-step explanation:
I believe that is the correct answer because it shows the answer is going to be m/h (meter/hour) so then you would just divide the meters over the hours.
768.57 / 41.1 = 18.7 m/h
36 because NQ is 18 and the tic mark means that each half is equal to each other, and 18+18=36 :D
