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.

The ratio of customers who purchase items with coupons to customers who don't use coupons is 6 to 16. If 9 customers use coupons

Irina-Kira [14]

Answer:

24 customers will not use coupons.

Step-by-step explanation:

Number of customers who use coupons = 9

Number of customers who don't use coupons = x

Ratio of customers who use coupons to customers who don't use coupons = 6:16

$=\frac{6}{16}$

$\frac{9}{x}=\frac{6}{16}$

$x=\frac{9\times 16}{6}=24$

24 customers will not use coupons.
