The two trains are the same distance from Chicago at 3pm, at that time both trains will have covered 240 miles
36, because 6^4 /6^2 is 6^2 and 6*6 (6^2) is 36
Answer:
Bottom right
First you multiply the bottom (2.5 x 1.5) to get 3.75. Then multiply 3.75 by 2 to got 7.5.
Whole equation: (2.5 x 1.5) x 2.0 = 7.5
You could put the ‘+6’ at the start of the equation so it would read as +6(x2+8x) and then expand the bracket as you normally would so you would get x2x6 which would get you 12x and then 6x8x which would get you 48x and then you could group both numbers together as they’re like terms and your final answer would be 60x
