10x^2+4x+6x^2
16x^2+4x
D is the correct answer.
Answer: Not really sure what you mean by algebra tiles but I do know that x=2.
Answer
Find out the what is the value of n.
To prove
By using the parallelogram property .
In parallelogram opposite angels are congruent .
As shown in the figure .
∠B = ∠ D
As given
∠B = (2n + 32)°
∠D = (4n - 2)°
(2n + 32) = (4n - 2)
solving the above
4n -2n = 32 +2
2n = 34

n = 17
Therefore the value of n is 17 .
