Answer:
-60
Step-by-step explanation:
Og problem: x(2x + 2x - 8y + 16)
Substitution: 3(6 + 6 - 48 + 16)

Answer:B
I think we are in the same class lol
Step-by-step explanation:448 divided by 14= 32
448 divided by 16= 28
B=speed of boat in water
Y= Speed of current
B+y=32
B-y=28
32 + 28 =60
60 divided by 2 = 30
32 -30 =2
B=30
Y=2
