Height of the flagpole = x
distance from flagpole to the mirror = 48 ft
height of Michele = 5 ft
distance from Michele to the mirror = 12 ft
Now, set the proportion.
x/48 = 5/12
48 * x/48 = 5/12 * 48
x = 240/12
x = 20
So, the height of the flagpole is 20 ft.

(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:
25
Step-by-step explanation:
2(25+20)=90. 25 plus 20 is 45 and 45 times 2 is 90
