One thing wrong is there is not closing parenthasees after x+1
and also, if you multiply it out, the answer is not 8x^2-8x-16 so the factored form given is worng
the real factored out form is 8(x-2)(x+1)
that person forgot the 8 in the front
Solution:
Find the LCM of 40 and 30 = 2
12:00 + 2 hours = 2PM
Final Answer:
They will ringt together at 2PM
Answer:
14 pint containers.
Step-by-step explanation:
First we have to convert gallon to quart.
2 gallons = 8 quarts
There are 2 containers that added up to 1 quart, so let's subtract the one quart from the 2 gallons(8 quarts), leaving behind 7 quarts.
The conversion between quarts and pints are 1qt=2pt, according to the key you provided. Then 7 quarts will equal to 14 pints. And therefore, she will need 14 pint containers.
Option C:
is the slope of the line
Explanation:
The line passes through the points
and 
We need to find the slope of the line.
The slope can be determined using the formula,

Where the coordinates
and
are
and 
Let us substitute the points in the formula
Thus, we have,

Simplifying, we get,

Adding the numerator and denominator, we have,

Cancelling the negative terms, we get,

Thus, the slope of the line is 
Therefore, Option C is the correct answer.
The midpoints between 4 and 8 would be 6 because 4 5 6 7 8, the middle term is 6
