1,2 and 3 because this three are positive numbers and when added and multipled both gives the same answer 6. 1,2 and 3 are the positive integers and the result of their addition and their multiplication is same .
so first you could combine common factors which are x2 and 6x. Subtract them and you get 4x. So your final answer would be 4x - 72 because you cant simplify anymore. 4x and 72 arent like terms so your final answer is 4x - 72.
so he talks three minutes each time he is on the phone so divide 37 by 3 to get 12.33 with the .33 repeated but you have to round down to 12 because you have to have a whole number for the calls but even if the number was 12.79 you cant round up to 13 because the number has to be over 13
