 Answer:

The value of 6(2b-4) when b=5 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 get6(2(5) - 4)= 6(10 - 4)…[solve parentheses]= 6(6)6 * 6 = 36=> 6(2(5) - 4) = 36Therefore, the value of 6(2b-4) is 36, when b=5.
