Question

Solve for the Area Please and Thank you

Answer 1

`k^4+10k^2+21`

Explanation:

`k^2 (k^2)` is the same as saying
`(k)(k)(k)(k)` and so it'll be
`k^4`. Combine
`7k^(2)` and
`3k^(2)` by adding them both to get
`10k^(2)`. Then multiply 7 by 3 to get 21. Therefore the area of the entire rectangle written in standard form as a polynomial is
`k^4+10k^2+21`. Write the polynomial with the highest degree being first to the lowest degree and that's how you write the polynomial properly.

Answer 2

8k^2+3
