" If matrix "A=[[1,3,x+2],[2,4,8],[3,5,10]]" is singular then find "x

If the matrix [(1,3,lamda+2),(2,4,8),(3,5,10)] is singular then find lamda

If the matrix [(1,3,lamda+2),(2,4,8),(3,5,10)] is singular then find lamda

If A = [[3-2x, x+1],[2, 4]] is singular, then find x.

Assertion (A) : If the matrix A=[{:(1,3,lambda+2),(2,4,8),(3,5,10):}] is singular , then lambda=4 . Reason (R ) : If A is a singular matrix, then |A|=0
