Step-by-step explanation:

The width, length and height are 4, 3 and 5 respectively. To find the volume we just multiply those 3 numbers together which gives us 60 cm³.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
