Question

Solve for the Area Please and Thank you

Answer 1

Answer:

$k^4+10k^2+21$

Step-by-step 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.
