Answer: -8x^3y^2 (choice B)
The coefficients multiply to 4 times -2 = -8
the x terms multiply to x^2 times x = x^(2+1) = x^3
The y terms multiply to y times y = y^(1+1) = y^2
So that's how I ended up with -8x^3y^2
Answer:
d
Step-by-step explanation:
3x+6=21
-6+21= 15
15÷3=5
240÷6=40 so the answer would be "The train is traveling 40 miles per hour."
