Verified Answer :

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.

Functions are written in terms of a variable. The resulting value of the function if b = 5 is 36

Functions and values

Given the function below

f(b) = 6(2b-4)

If the value of b is 5, hence;

f(5) =6(2(5) - 4)

f(5) = 6(10 -4)

f(5) = 6(6)

f(5) = 36

Hence the resulting value of the function if b = 5 is 36
