Answer

• 80. Commutative property: (-5)(-7) = (-7)(-5)

,

• 84. Distributive property:

[tex]3(4+5)=3\cdot4+3\cdot5[/tex]

Explanation

80.

Using the commutative property of the multiplication where:

[tex](a)(b)=(b)(a)[/tex]

We can apply it to our problem and get:

[tex](-5)(-7)=(-7)(-5)[/tex]

84.

Using the distributive property of the multiplication where:

[tex]a\cdot(b+c)=ab+ac[/tex]

We can apply it to our problem:

[tex]3(4+5)=3\cdot4+3\cdot5[/tex]
