Why is 9 a square number:
Nataly_w [17]
Square number actually means the product can be multiplied by the same number, for example
2 = 1x1
4 = 2x2
9= 3 x 3
so 9 can be square rooted so it's a square number
also 4x4 is 16 not 8 and 8x8 is 64 not 16 :)

QUESTION 1
podryga [215]

Answer: The team won 47 games.

Step-by-step explanation: The total games played was 84, and that means all games added together, but victories and losses. If the games they lost is called X, and the team won 10 more games than it lost, then it means the games they won is X + 10.

To find the value of wins and losses, we can now express both properly as;

X + (X +10) = 84

2X + 10 = 84

Subtract 10 from both sides of the equation

2X = 74

Divide both sides of the equation by 2

X = 37.

If the number of games won is X + 10, then games won is derived as

Wins = X + 10

Wins = 37 + 10

Wins = 47

The team won 47 games
