Question

What is the value of the expression 2 [2 (y – 52)] when x = b, y = 7, and z = ?

a) 02
b) 09
c) 17
d) 0 30

Answer 1

After substituting y = 7 into the expression and following the order of operations, the value of the expression 2 [2 (y - 52)] is found to be -180.

Step-by-step explanation:

To find the value of the expression 2 [2 (y – 52)] when y = 7, you first substitute 7 for y within the parentheses. This results in 2 [2 (7 – 52)].

Now, compute the value inside the parentheses: 7 – 52 equals -45. Then multiply -45 by 2, which is -90. Lastly, multiply -90 by 2, which gives you -180. Therefore, the expression evaluates to -180.
