If its length is 6x + 1 meters, what is its width?

Respuesta :

To determine the result of the product of the polynomials, we will use the distributive property:

[tex](a+b)(c)=ac+bc.[/tex]

Using the distributive property, we get:

[tex](3x+1)(2x^2+x+8)=3x*2x^2+3x*x+3x*8+1*2x^2+1*x+1*8.[/tex]

Simplifying the above result, we get:

[tex]6x^3+3x^2+24x+2x^2+x+8.[/tex]

Finally, adding like terms we get:

[tex]6x^3+5x^2+25x+8.[/tex]

Answer:

[tex]6x^3+5x^2+25x+8.[/tex]
