What is 5(4x+12)+3x+2

yulyashka [42]

Answer:

23 x + 62

Step-by-step explanation:

Simplify the following:

5 (4 x + 12) + 3 x + 2

5 (4 x + 12) = 20 x + 60:

20 x + 60 + 3 x + 2

Grouping like terms, 60 + 20 x + 3 x + 2 = (20 x + 3 x) + (60 + 2):

(20 x + 3 x) + (60 + 2)

20 x + 3 x = 23 x:

23 x + (60 + 2)

60 + 2 = 62:

Answer: 23 x + 62
