Answer:   x=55           y=145
x=55 
35+90=125
125-180=55
y=145
180-35=145
I hope this is good enough:
 
        
                    
             
        
        
        
Answer: 50 + m
Step-by-step explanation:
From the question, Erica and John are making brackets and Erica makes 25 bracelets while John makes m more bracelets than Erica. The total number of bracelets made will be:
Erica bracelet = 25
John bracelet = 25 + m
Total bracelet = 25 + 25 + m
= 50 + m
The expression that represents the total number of bracelets Erica and John made is 50 + m
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Hello There!
<u>Geometry</u>
The angles shown represented by the expressions (11x + 5) and (5x+59) are vertical angles
Vertical angles are congruent so we can use this equation to solve for x 
<u>Basic Algebra</u>
11x + 5 = 5x + 59
step 1 subtract 5x from each side 
5x - 5x cancels out 
11x - 5x = 6x
now we have 6x + 5 = 59
step 2 subtract each side by 5 
5 - 5 cancels out 
59 - 5 = 54
now we have 54 = 6x
step 3 divide each side by 6 
6x/6=x
54/6=9
we're left with x = 9 
now we want to plug in 9 into x for one of the expression
11(9) +  5 
11 * 9 = 99 
99 + 5 = 104
so we can conclude that the measure of the angle labeled ( 11x + 5 ) is 104 degrees
Now we need to find z 
<u>Geometry</u>
The angle with a measure of 104 and angle Z are supplementary angles meaning that the sum of the two is 180 
So to find z we subtract the known angle (104) from 180
180 - 104 = 76 
so we can conclude that z = 76
 
        
             
        
        
        
Answer:
(2z + 5)(2z - 3)
Step-by-step explanation:
4z² + 4z - 15
4z² + 10z - 6z - 15
2z (2z + 5) - 3 (2z + 5)
(2z + 5)(2z - 3)
