Answer:
160
Step-by-step explanation:
800 gallons in 5 days. The days is the denominator and the gallons are the numerator, whatever you do the the bottom you do to the top, so you divide the denominator by 5 and the numerator by 5 and you get 160 gallons per day. If you want to know how your answer is right, multiply 160 by 5
This is how your answer would look like in vertex form:
y= -2 (x - 1)^2 + 8
So your equation will be:
2(x+6) + 2(x+2) = 2(x+4) + 2(2x-2)
First, divide everything by 2
x+6+x+2 = x+4+2x-2
Then, combine like terms
2x+8 = 3x+2
Move the variables (the x's) to one side and the numbers to the other by subtracting 2x from one side and then 2 from the other
6 = 1x or 6 = x
Now that you know that x = 6, you go back to Earl's length and width equations
Length = x+2
Width = x+6
And plug in the value of x you got (6)
Length = 6+2 = 8
Width = 6+6 = 12
There are you answers! Hope this helped! (remember to add units, in this case the units are feet)
