Answer:
2x^2=3x+2
2x^2-3x-2=0
(x-2)(x+1/2)=0
x=2 or x=-1/2
The sum of 2 solution 2+-1/2=3/2
Step-by-step explanation:
Answer: 
This is the same as 
All we're doing is adding 'a' and
since the term "sum" is the result of adding two or more numbers.
One quarter of a number is the same as dividing by 4.
Example: one quarter of 28 = 
Since there is 16 cups in a US gallon, and there is 7 days in a week. First, you would multiply 1.5 times 7 getting 10.5 cups. But since that is not enough cups to be a gallon the division equation would look like this, 10.5/16 = ?. You can simplify it down to 5.25/8. Then, you get your answer of 0.65625 gallons.
Since angle 4x and 8x look like supplementary angles 4x+8x=180°. After solving that equation x=15. Plug that number in and 4x=60° and 8x=120°
