Let r1,…,rp be vectors in Rn, and let Q be an m×n matrix. Write the matrix [Qr1⋯Qrp] as a product of two matrices (neither of which is an identity matrix).

step-by-step explanation:

maya’s expression will generate the wrong sum because she violated the commutative property.

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
