(a) Using the completing the square method, we need to write into the form of where , so
Expand to find the value of c
Notice that we get back the first two terms, the and the .We need to get rid of the last term of '9' as the term was not in the original form. The final form will look like
Hence,
(b)
(c) , square root both sides plus and minus of 2 Hence
Answer:
I don't know if this is correct but id say
Step-by-step explanation:
the interest is 2 % so you'd say 2/100 times the amount of money in the interest so that is 2% of 5500
the interest is 110
(x + 2) = 3
-2 -2
0 1
x = 1
The area of a square is A=s^2
We already have the area, so we solve for the side length:
169=s^2
13=s
The perimeter of a square is P=4s
We plug in 13 for s:
P=4(13)
P=52
So the perimeter of the square is 52 m^2
Hope this helped!
