Given:

To find:
The product of the expression.
Solution:

Take out -4 as a common factor in Last two terms.

Make sure the terms in both brackets must be same.
Take out common factor (2y - 5) from both terms.

4 can be written as 2².

Using the identity: 
.
The product is
.
It is a function because all the inputs (x values) have one output (y value).
For something to be a function, inputs can only have ONE output, if an input has multiple outputs, it is not a function.
If different inputs have the same output, it is still a function because they don't have the same input value

Answer:
x=4
Step-by-step explanation:
Add 99 to both sides.
-4(x+5)=-45+9−4(x+5)=−45+9
Simplify -45+9−45+9 to -36−36.
-4(x+5)=-36−4(x+5)=−36
Divide both sides by -4−4.
x+5=\frac{-36}{-4}x+5=
−4
−36
Two negatives make a positive.
x+5=\frac{36}{4}x+5=
4
36
Simplify \frac{36}{4}
4
36
to 99.
x+5=9x+5=9
Subtract 55 from both sides.
x=9-5x=9−5
Simplify 9-59−5 to 44.
x=4
