Explanation:

The symbol that looks like an "E" is the uppercase greek letter sigma. It's used for summation. Specifically we are adding terms of the form -4+5n. What we do is replace n with values from the set {2,3,4,...,9,10}. After evaluating each item, we add up the results to get our final answer.

If n = 2, then -4+5n = -4+5*2 = 6 which is the first term.

If n = 3, then -4+5n = -4+5*3 = 11 is the second term

and so on until you reach n = 10.

A table is a handy way to keep track of everything (see below). Adding everything in the second column leads to the final answer of 234.

Answer: 234

Step-by-step explanation:

maitenant on considère un carré ABCD dont l'aire est 6,25 dm au carré quelle est la mesure de son côté AB justifier.
questin suivante
a.quelle est l'aire en dm au carré de chacun des carré de depart
b.quelle est l'aire du nouveau carré obtenu.
question6.on veut maitenant trouver la longueure exacte du côté du carré reconstitué sachant que son aire est 2dm au carré on recherche donc un nombre positif x tel que x ✖ x =x au carré =2 en faisant differents essais proposer une valeur décimal pour x puis 7 que peut-ton conclure.

For questions #9 - 11 "finding the slope" of a linear (straight) line, recall the "tools" that we can use:

1) Given a Graph: Slope or "m" = rise/run from one (x, y) point to a second (x, y) point on the line

2) Given any two (x, y) points on the line: Slope or "m" = y2 - y1 / x2 - x1

3) Given a "Table of Values": Choose any two (x, y) points in the table, then calculate the slope using the slope formula - Slope or "m" = y2 - y1 / x2 - x1

Find the sum.

A bunny had an infinite number of carrots. A group of bunnies tried to steal those carrots from him. The bunny decided to hide the carrots in a nearby cave. He dug up 100 holes and labeled them from 1 to 100 . Then he stored the carrots in the holes labeled as the multiples of 1 , 2 , 3 , . . . , 50. In other words, he stored a carrot in the holes labeled 1 , 2 , 3 , . . . , 100 . After that he stored a carrot in the holes labeled 2 , 4 , 6...100 . Next, he stored them in holes labeled 3 , 6 , 9 , . . . , 99 . And it went on. When he started storing the carrots in holes labeled as the multiples of 51 , the robbers came and took away all his carrots. How many carrots did he manage to save?
