Problem 37
<h3>Answer: B. 4 & 1/4 gallons</h3>
-------------------
Work Shown:
The 3/4 and 1/2 add up to (3/4)+(1/2) = (3/4)+(2/4) = 5/4 = 1&1/4
The whole part 1 is then added to the other whole parts 1 and 2 to get 1+2+1 = 4
Overall, the grand total is 4 & 1/4
An alternative way is to convert each mixed number to a decimal to get 1&1/2 = 1+1/2 = 1+0.5 = 1.5 and 2&3/4 = 2+3/4 = 2+0.75 = 2.75
Add up those decimals 1.5+2.75 = 4.25
then convert that result to a mixed number: 4.25 = 4+0.25 = 4+1/4 = 4&1/4

Problem 38
<h3>Answer: C. Cubic feet</h3>
----------------
The units for volume follow the template "Cubic _____" where you'll write "feet", "inches", "centimeters" or whatever unit you are using in the blank.
Some other examples:
* cubic miles
* cubic meters
* cubic yards
Answer:
-3(4+2n) multiply -3 by 4 and 2n
-12-6n
the answer is D. All points to the left of zero are negative.
The formula is there for area of a trapezoid.
1/2(4)(9 + 13)
2(22)
44
Subsitute to find out
actually, since it is odd degree and positive leading coefient, it goes from bottom left to top right
so as x goes to negative infinty, f(x) goes to negative inifnty
as x goes to positive inifnty, f(x) goes to positive inifnty
