Answer: 16 quarts.
Step-by-step explanation:
1 quart = 1/4 gallon.
4 quarts = 1 gallon.
If you have 4 gallons, then you need to multiply 4 by 4, because every gallon is equal to 4 quarts.
4 x 4 = 16.
Therfore, there are 16 quarts in 4 gallons.
The statements that are true based on the scatter plot and the given equation of line of best-fit are:
- In general, the line of best fit indicates that, the cost of a car insurance policy for a 21-year-old should be on average of about $315 less than the cost of a car insurance policy for a 20-yr-old.
- Car insurance policy cost tends to decrease as age of driver increases.
Given that the correlation coefficient of -0.951, it suggests that the policy cost and ages of the men as shown in the scatter plot are strongly negatively correlated.
This means that, the lower the higher the age of the men, the lesser the cost of a car insurance policy.
The slope value in the equation, y = -315.67x + 8986.5, is -315.67, which is the average cost of a car insurance policy per year.
Therefore, the statements that are true based on the scatter plot and the given equation of line of best-fit are:
- In general, the line of best fit indicates that, the cost of a car insurance policy for a 21-year-old should be on average of about $315 less than the cost of a car insurance policy for a 20-yr-old.
- Car insurance policy cost tends to decrease as age of driver increases.

(2x +y)(5x-y+3)
10x^2 - 2xy + 6x + 5xy - y^2 + 3y
10x^2 -2xy+5xy + 6x - y^2 + 3y
10x^2 +3xy + 6x -y^2 +3y
Looking at the answer boxes the sign looks wrong to me from y^2 ( a negative times a positive is a negative) I may be wrong.

Over 4 years, there will be a loss of 60,000 acres per year, so 60,000 times 4 is equal to 240,000 acres. 240,000 is positive because the problem asks for the change, not the increase.
This is the work you will show
c=-60,000(4)
c=-240,000
So -240,000 represents the change.
You could also just count by -60,000 four times.
-60,000-60,000-60,000-60,000=-240,000.
Work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
