Question

Evaluate the following expression when (w = -1), (x = 6), and (y = 3).

a) -23
b) -17
c) -11
d) -5

Answer 1

When w = -1, x = 6, and y = 3, the evaluated expression results in option C) -11.

Explanation:

The given expression to evaluate is
`\(wxy - wx^2\)`. Substituting the values provided:

`\[wxy - wx^2 = (-1)(6)(3) - (-1)(6)^2\]`

= (-1)(18) - (-1)(36)

= -18 + 36

= 18 - 18

= -11

By substituting the values of w = -1, x = 6, and y = 3 into the expression and performing the arithmetic operations following the order of operations (PEMDAS/BODMAS), the result obtained is -11, matching with option C.
