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.

Answer:
3) Prove the lengths are the same.
Step-by-step explanation:
Congruent is a measure of the lengths of the sides not the slopes.
height = tan(11) x 210
height = 40.81 yards
rounded to nearest tenth = 40.8 yards
