If `(a-5)^2+(b-c)^2+(c-d)^2+(b+c+d-9)^2=0`, then the value of `(a+b+c)(b+c+d)` is :

If   ( a -5 )^2 + ( b - c )^2 + ( c - d )^2 + ( b + c + d - 9 )^2 = 0 , then find the value of ( a + b + c ) ( b + c + d ) is

If [(2a+b, a-2b),(5c-d, 4c+3d)]=[(4,-3),(11,24)] , then value of a + b – c + 2d is:

If a : b = 2 : 5, b : c = 4 : 7 and c : d = 9 : 14, then the value of a : b : c : d is : यदि a : b = 2 : 5, b : c = 4 : 7 और c : d = 9 : 14, तो a : b : c : d कितना है ?

If [(2a+b,a-2b),(5c-d,4c+3d)]=[(4,-3),(11,24)] then the value of a+b-c+2d is (a) 8 (b) 10 (c) 4 (d) -8

If a b+b c+c a=0 , then what is the value of (1/(a^2-b c)+1/(b^2-c a)+1/(c^2-a b)) ? (a) 0 (b) 1 (c) 3 (d) a+b+c

If a,b,c,d are in G.P., then the value of (a-c)^2+(b-c)^2+(b-d)^2-(a-d)^2 is (A) 0 (B) 1 (C) a+d (D) a-d

If [(2a+b,a-2b),(5c-d,4c+3d)]=[(4,-3),(11,24)] , then value of a+b-c +2d is :

If (c)/(d)-(a)/(b)=x, a=2c, and b=5d , what is the value of (c)/(d) in terms of x?
