Question

If a = − 65 and b = 8, the product of a x b models which rule for multiplying integers? What is the product?

A) (+)(+) = +; The product is 520.
B) (−)(−) = +; The product is 520.
C) (+)(−) = −; The product is −520.
D) −(−)(+) = −; The product is −520.

Answer 1

c.ithat is the correct answer i hope it help

Answer 2

Given, a = -65 and b = 8.

We have to find multiplication of them.

a is negative and b is positive. When we multiply them, we know that the multiplication of positive and negative is negative. That means
`(+)(-) = -`.

So
`(a)(b) = (-65)(8)`

=
`(-)(+)(65)(8)` =
`- (65)(8)` =
`-520`

So we have got the required product.

Multiplication of a and b = -520.

The correct option is option C.
