-(b-5). Use the distributive property to write the expression as an equivalent algebraic expression

Dvinal [7]

Answer:

An equivalent algebraic expression of -(b-5) using distributive property is

-b+5

Step-by-step explanation:

We need to use distributive property to solve the expression -(b-5)

The distributive property states that $a(b+c)=ab+ac$

Using distributive property to solve the expression -(b-5)

$-(b-5)=-(b)-1(-5)\\=-b+5$

So, an equivalent algebraic expression of -(b-5) using distributive property is

-b+5

What does f(3) means ?

Butoxors [25]

F(x)=x^2+x+5

then

F(3) would be the function evaluated at x=3, or 17.

anytime you see F(3) it is just whatever formula you are looking at evaluated when the variable is equal to 3.
