Step-by-step explanation:
1. if the number of pages in the 1st day is 'x', then the 2d day - 'x+10', the 3d day - 'x+20', the 4th day - 'x+30', the 5th day - 'x+40' and the last day - 'x+50' pages;
2. if the sum of all the pages is 300, then it is possible to make up the equation:
x+x+10+x+20+x+30+x+40+x+50=300;
3. x=25, it means:
1st day - 25;
2d day - 35;
3d day - 45;
4th day - 55;
5th day - 65;
6th day - 75 pages.
The answer is 6,889. Squared just means the number times itself. In this case, it's 83 x 83. :)
Answer:
9,000
Step-by-step explanation:
1 km=1,000
9*1,000=9,000
If you mean |2-2| then the absolute value is 0
If you are talking about |2| |-2| then the absolute values are 2 and 2
