What's the answer? The other linked post does not give the OA. I think it's 3/8. The n(n+1)(n+2) will be divisible by 8 for three consecutive numbers, ie 6,7,8. Between 1 and 96, there are 12 numbers that are a multiple of 8. Given the expression, there will be 12*3 numbers that will be divisible by...

Gmat Prep - Algebra/Quadratic Problem

In the xy-plane, does the line with equation y=3x+2 contain the point (r,s)?

1. (3r+2-s)(4r+9-s)=0

2. (4r-6-s)(3r+2-s)=0

Thanks ssy, I had completely missed that relationship. When I saw this on my practice test, I knew I was missing an important relationship, but couldn't figure it out.

I don't understand what leads one to assume that this is a right triangle? To have the a:a*sqrt(3):2a relationship, it must be a right triangle.

What's the OA? I think the answer is A. My problem with D is that it's unclear as to what was lower, the actual costs or the rise in the costs.
