Question

What is the sign of a 2b when a=5 and b=2? Does the sign of the product depend on the sign of a,the sign of b, or the signs of both a and b? Explain

A.) when a=5 and b=2, the sign of a 2b is negative or positive

B.) -3*1/2*6=

Answer 1

a + 2b

Since, information is needed regarding the product, we must only consider 2b.

the answer of a multiplication equation is called product.

The sign of the product depends on the sign of b.
b = 2 so 2*2 = 4. the sign of four depends on whether b is positive or negative.

If b is positive then, 2 * 2 = 4 ; product is positive
if b is negative then, 2 * -2 = -4; product is negative

the sign of a has no bearing on the sign of the product of 2b.
