A knight on a chessboard is moved forward 3.6 cm from the centre of one square to another, then diagonally across at 45° to the centre of the destination square. How far
did the knight move in total? Give your answer to two decimal places.

where is the diagram? shown below where? ?

step-by-step explanation:

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.

step-by-step explanation:

in order to find the gcf of two numbers, first you need to find the prime factorization of each of the numbers. after you divide out the numbers as much as you can, you get:

36 = 2x2x3x3

84 = 2x2x3x7

from there, you can see which prime factors the two numbers have in common: 2, 2, and 3. then, you multiply the factors together to get 2x2x3=12.

you can double check this by dividing the two initial numbers by 12 to make sure 12 is a factor of them:

36/12 = 3

84/12 = 7

in your explanation, you pretty much give the definition of greatest common factors: that out of all the whole factors that 36 and 84 have in common, 12 has the greatest value.

hope this !
