Assume the smaller one is x, then the other ones will be x+2 and x+4

x(x+2) + 2 = 5(x+4)

x^2 + 2x - 5x - 18 = 0

-> x^2 - 3x - 18 = 0

-> (x-6)(x+3) = 0

-> x = 6 or -3, since x must be positive, then x = 6

So the numbers are: 6, 8, 10

If a ball rotates 110 degrees in 8 seconds, how many degrees does it rotate in 32 seconds?
Vlad1618 [11]
Well 32 divided by 8 would be 4 so... 32 x 4 would be 128 so 128 times. If it’s not correct I’m really sorry.

What number should be added to both sides of the equation to complete the square?<br> х2 + 3x = 6
Daniel [21]
3/2^2 or 0.75 because you have to take the middle value (3), divide it in half, then square it. That would be 0.75.
