mean =
let the third number be x , then
= 15 ( multiply both sides by 3 to clear the fraction )
34 + x = 45 ( subtract 34 from both sides )
x = 11 ← third number
Given that:
(x+2)(2x-5)=54
We have:
Using the quadratic formula, this is approximately 5.66, so rounded to the nearest whole number, our answer is 6.
