Hope this helps :)
(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: 4 and 8
Step-by-step explanation:
1. 12+7x=40
7x=28
x=4
2. 6x-3=45
6x=48
x=8
To solve this, you must define the variable first.
You can usually choose the variable to be what we are asked to find.
Let the number of people in the family be x.
The amount paid by each person (x) for admission and ride passes was $3.50+$5.50=$9.00
Only one payment for parking ($6) was made by the family.
The total amount spent was $9×x+$6
The total amount spent was $51.
Therefore, 5 people in the family went to the fair.
