Answer:
40z + 5
Step-by-step explanation:
I'm assuming you need to factor 32z + 4 + 8z + 3 - 4 + 2
- 32z + 8z ( since they both have the same variable ) = 40z
- 4 + 3 - 4 + 2 ( since they have to variables ) = 5

<h3>What is an 
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Two triangles are said to be congruent if they have the same shape and their corresponding sides are congruent.
Triangle ABC and triangle XYZ are similar based on angle-side-angle criterion.

Explanation:
Conversion of a quadratic equation from standard form to vertex form is done by completing the square method.
Assume the quadratic equation to be  where x is the variable.
 where x is the variable.
Completing the square method is as follows:
- send the constant term to other side of equal                  
- divide the whole equation be coefficient of  , this will give , this will give 
- add  to both side of equality to both side of equality 
- Make one fraction on the right side and compress the expression on the left side                                                                           
- rearrange the terms will give the vertex form of standard quadratic equation                                                                  
Follow the above procedure will give the vertex form.
(NOTE : you must know that  . Use this equation in transforming the equation from step 3 to step 4)

Answer:
∠ DFE = 15°
Step-by-step explanation:
The inscribed angle DFE is half the measure of its intercepted arc, that is
∠ DFE =  DE =
 DE =  × 30° = 15°
 × 30° = 15°
