O 44
0-28
O 28
O 44

Answer 1

644

Explanation:

`-216 * x - y`

We know that:

x = -3

y = 4

We can find the value of our expression by substituting x and y with the values given above. For example, instead of y, we'll put 4:

`-216*x - y\\-216*(-3) - 4\\`

Since -216 * -3 is equal to 648:

`648-4`

`644`

Answer: 644
