-5x•(2x^2+x+3) is the answer
Yes....because a terminating decimal can be turned into a fraction, making it rational
(10 + 9) x (3 - 1) x 2 = +75
19 x 2 x 2
76
76 > 75
To add a mixed number you must first convert it into a heavy headed fraction eg. 12/4
Then you must find a common denominator for all of the fractions like you normally do for regular addition of fractions
After you have added them you must convert the heavy headed fraction back into a mixed number by seeing how many times the numerator goes into the denominator
