Which are perfect square trinomials a) a 12a +36
b) x>- 35x + 50
c) 4x - 4x + 1
d) y² + 204-100
e) Iby², 32y + 16

add -60 to 120 which will result in : 2x+3y=180

then subtract 2x: 3y=-2x+180

lastly, divide by 2: y= -2/3x+60

hope this is the answer you're looking for: )

hi there!

not proportional because the 42 does not go into 120 and 3 does not go into 8.

correct proportion: $40/1 ticket.

the reason i say this is because 40/1 is simplified and it evenly goes into 120/3.

hope this : )
