There is no attachment so we don’t know what this angle is.
Let

, where

and let

be any real constant.
Given this definition of scalar multiplication, we can see right away that there is no identity element

such that

because
10. x*x + 10x + 21 = x + 3 * length
11. x*x + 2x - 8 = x + 4 * breadth
This is the expression bro!
100% sure
Plz mark me brainliest
Well how do you think i feel ?
