Answer 1

Answer: B. x^2 – x + 4

Step-by-step explanation: This answer is 100% correct for edge.nuity

Answer 2

2nd choice
`x^2-x+4` is correct.

Explanation:

We need to find about which polynomial is represented by the algebra tiles.

so we just need to collect all terms written on tiles then combine them.

Notice that - means -1 and + means +1

Row wise terms are:

`+x^2+x^2-x^2`

`-x-x+x`

`-x+x`

`-1+1+1+1`

`-1+1+1+1`

Now combine like terms:

`+x^2-x+4`

Hence 2nd choice is correct.
