First find the volume of the box:
V=2*2.2*2.5=11 cm^3
Then find the desity given by grams divided by volume:
density=25.6 g/ 11 cm^3 = 2.327 g/cm^3
Round to the nearest tenth, so 2.3 g/cm^3.
I hope that helped.
x= child
2x = adult
6.20x +9.80(2x) =593.40
6.20x +19.6x=593.40
25.80x =593.40
x=593.40/25.80 = 23

D, because the domain 8 is repeating therefore it isn’t a function
The answer is 65880000 and here are the steps
Area is calculated by multiplying length by width. Since we are given the width, we can test each length and see if the product matches the rectangle's area.
(2m - 3)(4m - 4) = 8m² - 20m + 12 ≠ 8m² + 4m - 12
(8m - 3)(4m - 4) = 32m² - 44m + 12 ≠ 8m² + 4m - 12
(2m + 3)(4m - 4) = 8m² + 4m - 12
(8m + 3)(4m - 4) = 32m² + 20m - 12 ≠ 8m² + 4m - 12
The length of the rectangle must be 2m + 3. Another method of solving this would be to divide the area by the width, or 8m² + 4m - 12 ÷ 4m - 4.
