8 is subtracted from 4 times the sum of 5 and 4.​

Step-by-step explanation:

8 is subtracted from 4 times the sum of 5 and 4.

Solution,

4(5+4)-8

4(9)-8

36-8

28

4(5+4)-8= 28

Step-by-step explanation: You start by using Distributive Property. So isolate the 4(5+4) from the subtracting 8. You will multiply the 4 on the outside of the parentheses by each number while keeping the sign in the middle. 4x5= 20 and 4x4= 16. So (20+16)-8, keeping the + sign. Now you use PEMDAS. Parentheses, Exponent, Multiply, Divide, Add & Subtract. In order from left to right. You will solve the equation in the parentheses first. 20+16=36, now 36-8. Which equals to 28. Your final answer.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
