Answer 2

Answer: The value of $6(2b-4)$ is 36.

Step-by-step explanation:

Given expression: $6(2b-4)$

To find the value of $6(2b-4)$ at b= 5, we need to substitute the b=5 in the expression, we get

$6(2(5)-4)\\=6(10-4).......[\text{solve parentheses}]\\=6(6)\\=6\times6=36$

$\\\Rightarrow6(2(5)-4)=36$

Therefore, the value of  $6(2b-4)$ is 36, when b=5.
