50 point HELP ASAP Question: A rectangle has sides measuring (3x + 8) units and (6x + 5) units.
cluponka [151]

Answer:

see below

Step-by-step explanation:

(3x + 8) units by (6x + 5) units.

A = l*w

  = (3x+8)(6x+5)

   Distribute

3x*(6x+5) + 8(6x+5)

18x^2 +15x + 48x +40

Combine terms

18x^2+63x+40  units^2

The degree is 2  ( the highest power of x)

This is a trinomial   ( it has 3 terms)

Multiplication is closed for polynomial multiplication

We started with polynomials and we ended up with a polynomial.
