Answer:
7y-4x.
Step-by-step explanation:
I think that the last 2 shouldn't be there and the third option should be 7y-4x or all the options are incorrect.
-3(2x- y) + 2y + 2(x+y)
= -6x+3y + 2y+2x+2y
= -6x+2x+3y+2y+2y
= -4x+7y.
Answer:
1,440,000
Step-by-step explanation:
1249 is rounded to 1200 because 49 is less than half of 100.
1194 is rounded to 1200 because 94 is more than half of 100.
1200 x 1200 = 1,440,000
