Question

PLEASE HELP ITS TIMED I DONT NEED BIG EXPLAINATION

Answer 1

Answer:

(C ) b(x)=4(x+2)(x−2)

Step-by-step explanation:

We are given

The number of blue tiles in her design is modeled by the function b(x)=$4x^2-16$

if the no of blue tiles used is zero then

b(x) =$4x^2-16$ = 0

       $x^2 = 16/4$ = 4

      x = +2 and -2

this is the condition for blue tiles

Modelling

b(x) = 4(x+2)(x-2)

This means when the blue tiles used are zero, then we use 2 red tile on each of the two square of 4 square. so the length will be 4 tiles long and its a square so 4x4 = 16 red tiles.
