Answer:
The perimeter of a face of the new cube is:
108 cm
Step-by-step explanation:
Original edge length of cube=9 cm
Increased edge length of the cube=9×3 cm
=27 cm
The perimeter of a face of a cube=4s
where s is the edge length of the cube
Perimeter of a face of new cube=4×27 cm
= 108 cm
Hence, the perimeter of a face of the new cube is:
60
K is the constant of proportionality or unit rate
(x, y)
(0, 0)
(2, 120)
(3, 180)
(4, 240)
120/2=60
180/2=60
240/2=60
The constant of proportionality or unit rate is 60

you first have to move 4x to the right side and then add 20 yo the left side to get what i got
