X = 75 is the answer is x+25=100
Another way to write this number is 626 children
Answer: height = 17.5cm
Step-by-step explanation: Peter mixes blue and yellow paint in the ratio 2:3, which means:


x = 12.6L
The container is full with the two paints, so total volume:
V = 12.6 + 8.4
V = 21L
Knowing that 1L = 1dm³ and sides of cuboid is measure in cm:
V = 21dm³ = 21000cm³
Volume of a cuboid is calculated as:
V = width*length*height
Height of the container is
height = 
height = 
height = 17.5cm
The height of the container is 17.5cm.
In standard form, zero is always on the right:
y = 12 - x^4
y + x^4 - 12 = 0
End behavior:
As x approaches ∞, y approaches -∞
As x approaches -∞, t approaches -∞
