Answer: OPTION A.
Step-by-step explanation:
For this exercise is important to remember the multiplication of signs:
[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]
Given:
[tex](-3.2)(1.7)[/tex]
You can observe that one factor is negative and the other one is positive, therefore, the result will be negative.
You can write the numbers as below:
[tex]3.2 *\\1.7\\----[/tex]
The steps are:
1. Multiply each digit of [tex]3.2[/tex] by each digit of [tex]1.7[/tex]
2. Add the products and do not forget to write the negative sign.
3. Since the [tex]3.2[/tex] has one decimal place and [tex]1.7[/tex] has one decimal place, the sum of the products must have 2 decimal places.
Then:
[tex]3.2 *\\1.7\\----\\224+\\32\\----\\-5.44[/tex]
