Exercise 24 Page 239

Substitute 3 for c in the expression. When multiplying real numbers, the product will be positive if the signs are the same and it will be negative if the signs are different.

-15

Practice makes perfect

To evaluate the given expression for c=3, first, we should substitute 3 for c in the given expression.

-5c

c= 3

-5( 3)

When multiplying real numbers, the product will be positive if the signs are the same and it will be negative if the signs are different. cc Same Sign & Different Signs (+)(+)=(+) & (+)(-)=(-) (-)(-)=(+) & (-)(+)=(-) In our case one number is negative and one is positive, so the product will be negative.

-5(3)

(- a)b = - ab

-5* 3
