SpyIntel [72]3 years ago
4 0

Step-by-step explanation:

Number of sides of the given polygon, n =5

Sum of interior angles =( n-2)180°

=( 5 - 2)180°

= 3*180°

= 540°

Missing angle, x = 540°- (100°+105°+110°+145°)

= 540°- 460°

= 80°

Which geometric model using algebra tiles represents the factorization of x2 – 5x 6? An algebra tile configuration. 4 tiles are
son4ous [18]

The statement for geometric model using algebra tiles represents the factorization is the statement number 2.

<h3>What is algebra tile?</h3>

Algebra tiles used to represent the algebraic expression in the table form. The shape of algebra tile is square and rectangle, in which the variables represented.

The given polynomial equation in the problem is,

x^2 -5x+6

In the above polynomial, the highest power of variable is 2. Thus, it is a quadratic equation.The image of the algebra tile for the given polynomial attached below.

The statement which satisfy the polynomial and its algebra tile is,

An algebra tile configuration.

  • 3 tiles are in the Factor 1 spot: 1 is labeled x and 2 are labeled negative.
  • 3 tiles are in the Factor 2 spot: 1 is labeled x and 2 are labeled negative.
  • 11 tiles are in the Product spot: 1 is labeled x squared, 4 are labeled negative x, and 6 are labeled.

Thus, the statement for geometric model using algebra tiles represents the factorization is the statement number 2.
