Evaluate the following expression using the given values of the variables.
1/2h(b+B);h=4,b=9,B=18
We substitute the given values into the expression:
1/2 * 4 * (9 + 18)
First, we simplify the expression within the parentheses:
1/2 * 4 * 27
Next, we multiply:
2 * 27
Finally, we multiply:
54
Therefore, the value of the expression is 54.
To evaluate the expression 1/2h(b+B), we substitute the given values of the variables:
h = 4, b = 9, B = 18
1/2 * 4 * (9 + 18)
We start by simplifying the expression inside the parentheses:
1/2 * 4 * 27
Now we can multiply:
(1/2) * 4 * 27
Multiplying 1/2 by 4 gives us 2:
2 * 27
Finally, we multiply 2 by 27:
54
Therefore, the value of the expression 1/2h(b+B) when h = 4, b = 9, and B = 18 is 54.
