Answer:

[tex](-7)(-1.2)\leftrightarrow 8.4[/tex]

[tex](-2\frac{1}{2})(-2)\leftrightarrow 5[/tex]

[tex](2.5)(-2)\leftrightarrow -5[/tex]

[tex](7)(-1.2)\leftrightarrow -8.4[/tex]

Step-by-step explanation:

Product rule of signs:

(+)(+) = (+)

(+)(-) = (-)

(-)(+) = (-)

(-)(-) = (+)

Using these signs simplify the given expression.

[tex](-7)(-1.2)=8.4[/tex]

It means (-7)(-1.2) is equivalent to 8.4.

[tex](-2\frac{1}{2})(-2)=(-\frac{5}{2})(-2)=5[/tex]

It means [tex](-2\frac{1}{2})(-2)[/tex] is equivalent to 5.

[tex](2.5)(-2)=-5[/tex]

It means (2.5)(-2)- is equivalent to -5.

[tex](7)(-1.2)=-8.4[/tex]

It means (7)(-1.2) is equivalent to -8.4.
