The students in math class use square tiles to make arrays. If they
- use 8 (8=1·2·2·2) tiles, then they can form arrays of the length in 1 tile, 2 tiles, 4 tiles and 8 tiles;
- use 9 (9=1·3·3) tiles, they can form arrays of the length in 1 tile, 3 tiles and 9 tiles (one array less).
So, you can conclude that Celia is correct.
Answer:
B
Step-by-step explanation:
Answer:
4p^2 +6p -8
Step-by-step explanation:
2 p^2 + 3 p - 4 less (-2 p^2 - 3 p + 4)
2 p^2 + 3 p - 4 - (-2 p^2 - 3 p + 4)
Put in vertical format
2 p^2 + 3 p - 4
- (-2 p^2 - 3 p + 4)
------------------------------
Distribute the minus sign
2 p^2 + 3 p - 4
+2 p^2 + 3 p - 4)
------------------------------
4p^2 +6p -8
