2(6×7)+[32]-25 too complicated for me lol

Let's attempt this with more of a "can do" attitude, OK? :)

2(6×7)+[32]-25 needs to be evaluated following order of operations rules (PEMDAS). Here, we must multiply before either addition or subtraction, and in particular should multiply that 6*7 first because it's inside parentheses.

2(42) + 32 - 25 becomes:

84 + 32 - 25 = 91 (answer).

i think the answer is b.

step-by-step explanation:

not 100% sure though.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
