MathematicsHard249×since 2002Q2608Let the equation of plane passing through the line of intersection of the planes x+2y+az=2x+2 y+a z=2x+2y+az=2 and x−y+z=3x-y+z=3x−y+z=3 be 5x−11y+bz=6a−15 x-11 y+b z=6 a-15x−11y+bz=6a−1. For c∈Zc \in \mathbb{Z}c∈Z, if the distance of this plane from the point (a,−c,c)(a,-c, c)(a,−c,c) is 2a\frac{2}{\sqrt{a}}a2, then a+bc\frac{a+b}{c}ca+b is equal to :A−-−2B4C2D−-−4Check answerSkip
