You roll a number cube numbered from 1 to 6. what is the probability that the number is divisible by 2? as a decimal

x = 3 ± √(5+y)

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
