Step-by-step explanation:
5x+52=9x+20
subtract 5x on both sides
subtract 20 on both sides
32=4x
divide by 4 on both sides
x=8
plug in x to the equations for A, D, and C
A and D are 92°
C is 56°
B and C will add up to 90, so
90-56=34°
13y-6=34
add 6 on both sides
13y=40
divide by 13
y=40/13 (I don't wanna calculate that)
 
        
             
        
        
        
Six point eight four.
(Note, you don't say, "Six point eighty-four" As it doesn't sound correct.

Answer:
The answer to your question is 2x² - 29x + 26
Step-by-step explanation:
dividend =  6x³ - 25x² + 20x + 4
divisor    =  3x + 2
                              2x² - 29x + 26
                3x + 2    6x³ - 25x² + 20x + 4
                             -6x³ -   4x²  
                               0   - 29x² + 20x
                                    + 29x² + 58x
                                        0         78x + 4
                                                  -78x - 52
                                                     0   - 48
quotient =   2x² - 29x + 26
remainder = -48
Result =  2x² - 29x + 26 - 48/6x³ - 25x² + 20x + 4
 
        
             
        
        
        
 Yes, solutions, roots, x-intercepts, and zeros are the same thing.

What is a quadratic equation?</h3>
The general quadratic equation is given by:
a*x^2 + b*x + c = 0
So the solutions are the values of x such that the above thing is zero.
On another hand, a parabola or a quadratic function is given by:
a*x^2 + b*x + c = y
The roots, zeros, or x-intercepts (these represent the same thing) are given by:
a*x^2 + b*x + c = 0
- Zero or Root means that when you evaluate the function in that value the outcome is zero.
- X-intercept means that for that value of x, the function intercepts the x-axis, so the function is equal to zero.
So these are the values of x such that the function becomes equal to zero, so these are exactly the same thing as the solutions of a quadratic equation.
Concluding, yes, solutions, roots, x-intercepts, and zeros are the same thing.
