Answer:

The sign is negative

Step-by-step explanation:

Given

Expression = 3xy

x > 0

y

Required

Determine the sign

The expression can be split into 3 factors

(3) (x) (y)

If x > 0 then x is positive and If y < 0 then y is negative

So, the expression becomes:

(+3) (+x) (-y)

<em />

Leave only signs

(+) (+) (-)

+ * + = -

So, we have:

(+*+) (-)

(+) (-)

+ * - = -

So, we have:

(+) (-) = -

<em>Hence, the sign of the expression is negative</em>

<em></em>

Take for instance;

x = 2

y = -4

The expression would be:

3 *2 * - 4 =-24 -- negative
