Answer:
 They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.
 
        
             
        
        
        
Step-by-step explanation:
angle J is also 67 deg since the triangle is an isosceles triangle 
angle T is 67 deg since the 2 triangles are congruent 
angle G = 180 - 2x67 = 46 deg
ST is 5cm
HJ is 3.7cm

                A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC.

To find the length of a line given two points, we are going to use the distance formula, which is defined below:

( and
 and  are the two points)
 are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:

- Substitute values into formula

- Combine like terms and then simplify  to 0 to 0

- Compute  

- Compute  
The length of DC is 3.
