DeShawn placed a square photo in the center of the screen as shown. Dilate the photo so that it results in
the picture taking up the whole screen. What is the
scale factor? Label each point with the new
coordinates.

answer is x<

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

other answer is correct. i had used the radius of the radius somehow. a website:
