Simplify. b (−3)∙(2a+b)−4(b−a) plz and

-6ab-3b^2-4b+4a

Step-by-step explanation:

Split the problem in half: b (−3)∙(2a+b)    −4(b−a)

Solve the first half:

b(-3) = -3b

-3b x -2a = -6ab

-3b x b = -3b^2

First Half: -6a-3b

Solve the second half:

-4 x b = -4b

-4 x -a = 4a

Second Half: -4b+4a

Put it all back together: -6ab-3b^2-4b+4a

your answer would be 12

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
