Are you supposed to find B?
During Distributive property, the number on the outside of the parenthesis basically gets multiplied by the numbers inside the parenthesis. In this case, you would multiply 6 by 5 and 4. When you get the products, then follow the sign that comes next. In this case, you would add the products to get a total sum. I attached a photo for further reference.
Hope this helps!
Answer:
Modification has not reduced the number of accidents.
Step-by-step explanation:

A B C D E F G H
Before modification 5 7 6 4 8 9 8 10
After modification 3 7 7 0 4 6 8 2
Difference -2 0 1 -4 -4 -3 0 -8
Mean of differences 
Standard deviation of differences = 
Formula of paired t test :

Df = n-1 = 8-1 =7

t critical> t calculated
So, We failed to reject null hypothesis
Hence modification has not reduced the number of accidents.
we are given

we can also write it as

now, we can use factor formula

we can use above formula
we get

now, we can simplify it

now, we can set it to 0

and then we can solve for x




now, we can use quadratic formula

now, we can plug values
and we get


So, we will get solution as

Answer:
2/(3a^(1/3))
Step-by-step explanation:
The derivative of g(x) = 2/(3x^(1/3))
you get this by bringing the exponent of g(x) down and the new exponent is (2/3) - 1 .
Then replace x with a
