Answer:

16.5 square units

Step-by-step explanation:

area(trapezoid) = ((b1 + b2) / 2)(h)

base 1: 9

base 2: 3

height: 3

area = ((9 + 3) / 2)(3)

area = (11/2)(3)

area = (5.5)(3)

area = 16.5

Which polynomial expression represents the area of the outer most square tile, shown below?

Andrew [12]

ANSWER

${x}^{2} - 6x + 9$

EXPLANATION

The outermost square tile has side length,

$l = x - 3$

The area of a square is given by;

$Area= {l}^{2}$

We substitite the given expression for the side length into the formula to obtain,

$Area= {(x - 3)}^{2}$

$Area= {(x - 3)}(x - 3)$

We expand using the distributive property to obtain;

$Area=x {(x - 3)} - 3(x - 3)$

This gives us:

$Area= {x}^{2} - 3x - 3x + 9$

$Area= {x}^{2} - 6x + 9$

The last choice is correct.
