Answer:
Sam will need 54 ft of cement
Step-by-step explanation:
The formula for the volume of a rectangular prism is length (l) x width (w) x height (h). In this problem, the length is 9, the width is 3 and the height is 2. Multiply 9x3x2 to get the volume of the hole and you'll get 54.
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 = -6, 4
Step-by-step explanation:
Convert into factored form :
(b+6)(b-4)
Then make one of the terms 0.
