If `|x2 18 x|-|6 2 18 6|` , then x is equal to (A) 6 (B) `+-6` (C)`-6` (D) 0

If det[[x,218,x]]=det[[6,218,6]], then x is equal to (A)6(B)+-6(C)-6(D),0]|

Evalute the determinants in queations 1 and 2 : If |{:(x,2),(18,x):}|=|{:(6,2),(18,6):}| , then x is equal to : (a) 6 (b) +-6 ( c) -6 0

If |{:(x,2),(18,x):}|=|{:(6,2),(18,6):}| then x is equal to

If ( -6 ) ÷ x = 1 , then x is equal to (A)   -6   (B)   6   (C)   -1/6   (D)   7

If the curve a y+x^2=7 and x^3=y cut orthogonally at (1,\ 1) , then a is equal to (a) 1 (b) -6 (c) 6 (d) 0

If |2x5 8x|=|6-2 7 3| , then x= (a) 3 (b) +-3 (c) +-6 (d) 6

(-2)x\ (-3)x\ 6\ x\ (-1) is equal to (a)36 (b) -36 (c) 6 (d) -6

If 6x = 18, then 18x = 54

If [{:(x,2),(18,x):}]=[{:(6,2),(18,6):}] , then 'x' is equal to +-6 .

If |(x,2),(18,x)| = |(6,2),(18,6)| , then the value of x is:
