Question

Evaluate the expression, if x=4, y=9, and z=7.
x(y + z - 3 squared)

Answer 1

After evaluating the expression with the given values for x, y, and z by following the order of operations, the final result of the expression is 28.

Step-by-step explanation:

To evaluate the expression given x=4, y=9, and z=7, we follow the order of operations, which means we perform the operations inside the parentheses first before multiplying by x.

First, calculate the value inside the parentheses as follows:

y + z - 3 squared

= 9 + 7 - 32

= 9 + 7 - 9

= 16 - 9

= 7

Now, multiply this result by x:

x(y + z - 3 squared)

= 4(7)

= 28

So, the evaluated expression equals 28.
