Answer:
5 Commemorative coin packs
3 coin holders
Step-by-step explanation:
X^2 - 2x + 4
= (x - 1)^2 - 1 + 4
= (x - 1)^2 + 3
2x+3=5x-14
-2 -2
3=3x-14
+14
17=3x
/3 /3
X=5.6.... round up 5.7
2(5.7)+3= 14.4
YZ=14.4
Answer: there were 15 tiles in each box
Step-by-step explanation:
Let the number of tiles in each full box be x
Suppose, instead, that Bruce used 6 full boxes of tiles plus an additional 2 tiles. It means that he used a total of
(6x + 2) tiles
Suppose, that Felicia used 5 full boxes of tiles plus an additional 17 tiles. It means that he used a total of
(5x + 2) tiles.
If they each used the same number of tiles, it means that the total number of tiles used by Bruce = total number of tiles used by Felicia. Therefore,
6x + 2 = 5x + 17
6x - 5x = 17 - 2
x = 15
