The number added to the polynomial is
Explanation:
The given polynomial is
We need to determine the number that is added to the polynomial to complete the square.
The last term of the polynomial can be determined by dividing the term 21 by 2 and then squaring the term.
Thus, we have,
Last term =
Now, squaring the term, we have,
Last term =
Thus, the number added to the polynomial by completing the square is
You need to first calculate the amount of lost money, which is 86-60.2=25.8 To find the discount, you need to put this over the initial price, or 86. This equals 0.3, which is 30 percent.
The best way to get this answer would be to divide 15 by 26, getting 0.576923077, then multiplying that number by 100, getting 57.6923077, then you round it to the nearest whole number if needed. The answer to the nearest whole number is 58%.
Answer:
See explaination
Step-by-step explanation:
B. The equality relation on the real numbers is an equivalence relation.
This statement is true
C. If RR is a reflexive relation on a set S, then any two RR- related elements of S must also be R2R2 related.
This statement is true
F. The less than or equal relation on the real numbers fails to be an equivalence relation because it is reflexive and transitive but not symmetric
This statement is true
H. If RR is an equivalence relation, then R2
This statement is true
