Question

What is the value of 6(2b-4) when b = 5?

Answer 1

the value is -4

Explanation:

6(2b-4) b=5 so plug that in

6(2(5)-4) distribute 2 to 5 (multipy 2 and 5)

6(10-4) now, distribute 6 to 10 and -4 (multiply 6 by 10 and -4)

60-240 then, divide -240 by 60

-4 is your answer

Answer 2

`6(2b-4) when \: \: b = 5 \\ 12b - 24 \\ b = 5 \\ 6(2(5)-4) \\ 6(10 - 4) \\ 6(6) \\ 36`
