13.28
This is what she had before she started cleaning
Answer:
well does it have the repeating line on top? if it does then it's irrational if it doesn't it's rational

Answer:
x = -6 , -2
Step-by-step explanation:
Find factors of x² and 12, in which, when combined, will give 8x:
x² + 8x + 12 = 0
x 6
x 2
(x + 6)(x + 2) = 0
Check. Use the FOIL method:
First, combine the first terms: x * x = x²
Next, combine the outside terms: x * 2 = 2x
Then, combine the inside terms: 6 * x = 6x
Finally, combine the last terms: 6 * 2 = 12
Combine like terms: x² + (2x + 6x) + 12
x² + 8x + 12
Solve for the solutions. Set each parenthesis equal to 0:
(x + 6)(x + 2) = 0
(x + 6) = 0
(x + 2) = 0
Isolate the variable x. Subtract 6 & 2 from both sides for their respective equation:
x + 6 = 0
x + 6 (-6) = 0 (-6)
x = 0 - 6
x = -6
x + 2 = 0
x + 2 (-2) = 0 (-2)
x = 0 - 2
x = -2
x = -6 , -2

Answer:
160
Step-by-step explanation:
Each cube is 1/2 inch, so there will be 2 cubes in each 1 inch of length. The dimensions of the prism in terms of the number of cubes are ...
length: 4 in ⇒ 4×2 = 8 cubes
width: 2 in ⇒ 2×2 = 4 cubes
height: 2 1/2 in ⇒ (2 1/2)×2 = 5 cubes
Then the number of cubes required to fill the prism is ...
8 × 4 × 5 = 160 . . . . cubes
The volume of the prism is equivalent to that of 160 1/2-inch cubes.
