You need to estimate the square root of 200 ft². Rewrite 200 as 2 x 100, then square root of (2*100) is:
10*sqrt(2). The sqrt(2) = 1.414, so the length of each side of the square will be 10*1.414 = 14.14 ft or about 14 ft.
Answer:
p = 4
Step-by-step explanation:
Given equation:
<u>Standard equation of a circle:</u>
(where 
is the centre of the circle, and 
is the radius)
If you expand this equation, you will see that the coefficient of 
is always one.
Therefore, 
<u>Additional information</u>
To rewrite the given equation in the standard form:
So this is a circle with centre (2, -3) and radius √29
Standard form is Ax + By = C
Where A is a positive integer
The y needs to be moved to the left side so subtract 3y from both sides.
2x - 3y = -8
c
All the information you need is in the quadratic trinomial ... Read from right to left:
Find factors of 49 which ADD (+) to give 14.
These will be 7
