The sum of the pages numbers of a book is 85. what are the page numbers of two facing pages of the book. If the sum is not given, but the product is given to be 1806,how will you find the page numbers? ?Guy's plz help me ​

Answer 1

Answer:

42 and 43

Step-by-step explanation:

Let the pages be x and x+1

x+x+1 = 85

2x = 85-1

2x = 84

x = 84/2

x = 42

So the page numbers are 42 and 43

IF SUM IS NOT GIVEN AND PRODUCT IS GIVEN :

x(x+1) = 1806

x²+x-1806 = 0

By splitting middle term

x²+43x - 42x - 1806 = 0

x(x+43)-42(x+43) =0

(x-42)(x+43) = 0

x = 42

So the pages are 42 and 43

Answer 2

Step-by-step explanation:

If you have a fever, cough and difficulty breathing, seek medical attention, but call by telephone in advance if possible and follow the directions of your local health authority. Why? National and local authorities will have the most up to date information on the situation in your area. Calling in advance will allow your health care provider to quickly direct you to the right health facility. This will also protect you and help prevent spread of viruses and other infections.
