Step-by-step explanation:
The given quadratic equation is :

The formula to solve a quadratic equation is :

Put a = 13, b = 10 and c = 1
So,

Hence, this is the required solution.
F= 9t . This is because each square foot is 9 tiles so however many square feet would be t. For ex. If you wanted 3 square feet then it would be f= 9(3) f=27 so you would need 27 tiles
Answer:
9/100
Step-by-step explanation:
Answer:
3440
Step-by-step explanation:
The total number of people polled is 150.
The total number of people who said they'd vote for Candidate #2 is 78.
The number of undecided voters is 7.
Assuming undecided voters don't vote, Candidate #2 can expect to win 78/143 = 54.5% of the votes.
75% of the 8400 registered voters will vote, or 6300.
So Candidate #2 can expect to win 3440 votes.
