Given:
The equation for the area of the first option is:

Where x is the side length of the current square park.
To find:
The side length of the current square park.
Solution:
We have,

It can be written as:

Splitting the middle term, we get




We know that the side length of a park cannot be negative. So, the only possible value of x is 320.
Therefore, the most direct method to solve the given equation is splitting the middle term and the side length of the current square park is 320 meters.
Answer:
45
Step-by-step explanation:

ssubstitute a and b for any of the numbers (3 or 6) and get 36+9 which is 45
45 =

so you would need to find the square root to get c
D because it has to be a chord due to being perpendicular to a diameter
Answer:
5.1304 x 10^14
Step-by-step explanation:
there is 10 zeros behind the decimal point plus 4 other decimal places
in a scientific notation the number has to be less then 10 but more then 1
Answer:
x = 2 or
x = -7
Step-by-step explanation:
(x - 2)(x + 7) = 0
x - 2 = 0
Add 2 to both sides
x - 2 + 2 = 2 + 0
x = 2
OR
x + 7 = 0
Subtract 7 from both sides
x + 7 - 7 = 0-7
x = -7
Therefore
x = 2 or
x = -7
