If `| [ 2x , 5 ] , [ 8 , x ] | = | [ 6 , -2 ] , [ 7 , 3 ] |` , then find x

If |[2x,5],[8,x]|=|[6,5],[8,3]| then x is

If the mean of 6,8,5,7, x and 4 is 7 then find x

If the median of the data , x_(1) , x_(2) , x_(3) , x_(4) , x_(5) , x_(6) , x_(7) , x_(8) is a , then find the median of the data is x_(3) , x_(4) , x_(5) , x_(6) . (where x_(1) lt x_(2) lt x_(3) lt x_(4) lt x_(5) lt x_(6) lt x_(7) lt x_(8) )

If |{:(2x,5),(8,x):}|=|{:(6,-2),(7,3):}| , then the value of x is

Find the angle between the planes : (i) 3 x - 6y - 2z = 7 " " 2x + y - 2z = 5 (ii) 4 x + 8y + z = 8 " " and y + z = 4 (iii) 2 x - y + z =6 " " and x + y + 2z = 7 .

If |(2x,5),(8,x)|=|(6,-2),(7,3)| then the value of x is

5x + 2(x + 7) = 14x – 7. Find 3x - 6 ?

Find the value of x , [ [3, 4],[5, 6]] + [ [2, 1],[x, 1]] = [ [5, 5],[8, 7] ]

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