Question

20 POINTS+BRAINLIEST 8TH GRADE MATH PART 4: Imaginary operations- please explain how you came to the answer because this doesn't make sense

Answer 1

[]b = 6b - 12

we can start by seeing that b is being multiplied by 6 so we should do the same to 4.

6 * 4 = 24

Next we see that 12 is being subtracted from b so we should do the same to 4.

24 - 12 = 12

Therefore, 12 is your final answer.

Answer 2

The correct is B (12). So []b =6b-12 which means that the expression is just 6*the number -12. So, when you substitute 4 in for b it would turn into 6*4-12 which is 24-12 or 12.
