3. Deborah notices that the polynomial 602 + x - 40 follows the structure of a
quadratic, so she tried to factor it using an area
model. Help her figure out what values go in
the boxes.
6x4
-40
Enter the negative value in the blue box.
Grey Box:
2
Blue Box:

true

step-by-step explanation:

range is infinite on both x and y axis positive and negative

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
