Answer: -(x + 3)^2 = 3
Explanation:
-x^2 - 6x + 6 = 0
-x^2 - 6x = -6
-x^2 - 6x + 9 = -6 + 9
-(x + 3)^2 = 3
Answer:
See below.
Step-by-step explanation:
There are three sheets of 10 stickers. This is equal to 30 stickers. There are also 30 single stickers. Split the single stickers and give Gary and Jill 13 each. Then Gary and Jill can each take a sheet of 10. They will both have 23 stickers.
So there is a total of 6 ears, 12 paws, and 3 tails in the room.
Ratio:
Red : Total
2 : 5
(x2) (x2)
4 : 10
Green : Total
3 : 10
Total of red and green marbles = 4 + 3 = 7
Blue marbles = 10 - 7 = 3
10 parts = 40 marbles
1 part = 40 ÷ 10 = 4
3 parts = 4 x 3 = 12
Answer: There are 12 blue marbles.
Answer:
