Answer:

It often operates in maths without any equivalent concepts and methods throughout the real world. In some cases, computational processes and approaches are applied in different fields without a great understanding of the essence of the process. Another argument is the use of formal logic as well as the accuracy of evidence extracting.

B. Simplify: 3(x+2) = 4x ( +2 points)
olya-2409 [2.1K]

Answer:

6

Step-by-step explanation:

3(x+2) = 4x

3x + 6 = 4x  <- you times the x and 2 that is inside of the parentheses by the 3 that is on the outside

3x - 3x + 6 = 4x - 3x  <- you have to subtract the 3x from the left side and you have to do the same on the right so you can get the numbers alone.

6 = x
