The correct answer would be C.
In order to solve for this you must first get the equation equal to 0. Luckily for you, it already is in that form.
Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.
a = 4 (because it is the coefficient to x^2)b = -6 (because it is the coefficient to x)c = 1 (because it is the end number)
Now we can plug these values into the quadratic equation.



And those would be your two answers
The area of the plot is 600 (20x30) and it needs to be 1200 (600x2)
only the width is changed so you divide it by the length which is 30
1200 divided 30 is 40 so the answer is 40 (another way is to just multiply the width by 2 since it's the only thing changing)
hope this helps :)
Answer:
B
Step-by-step explanation:
You don't have do do anything with the denominator because they are the same so simply subtract!
- 9 - 4 = 5
- 7 - 3 = 4
- The denominator stays the same
- 5

- Simplify
= 5
