Answer:
37, 38, and 39
Step-by-step explanation:
Write the equation by converting words into math symbols:
- consecutive means n, n+1, and n+2
- subtract -
- product *
- result is =
This means "the product of the smaller two" is n(n+1).
This also means "the product of the greater two" is (n+1)(n+2)
They are subtracted from each other and equal to 76. So it becomes
(n+1)(n+2) - n(n+1) = 76
Write and solve:
![(n+1)(n+2) - n(n+1) = 76\\n^2+n+2n+2-n^2-n=76\\n+2n+2-n=76\\2n+2=76\\2n=74\\n=37](https://tex.z-dn.net/?f=%28n%2B1%29%28n%2B2%29%20-%20n%28n%2B1%29%20%3D%2076%5C%5Cn%5E2%2Bn%2B2n%2B2-n%5E2-n%3D76%5C%5Cn%2B2n%2B2-n%3D76%5C%5C2n%2B2%3D76%5C%5C2n%3D74%5C%5Cn%3D37)
The smallest number is 37. The next is 38. The last is 39.
