The base is a square, therefore all the sides of the base  are the same. This also means all the triangles have the  same area.
10*10 = 100 cm^2 for the base
0.5*10*12 = 60 cm^2 for each triangle
100 + 4(60) = 340 cm^2
        
                    
             
        
        
        
The student with the most accurate description of the graph that represents Kate's movement is Tim
<h3>The student with the accurate description</h3>
From the graph that represents Kate's distance per minute, we have the following highlights:
- Kate drives at an irregular speed for 2 minutes
- Then she drives at a regular speed for 4 minutes
- Then she stopped moving for the next 2 minutes
The student's description that matches the above highlights is Tim
Hence, the student with the most accurate description is Tim

Answer:
The answer is 939
Step-by-step explanation:
If you divide 939 by 9 it equals 104 R3. 
If you divided 939 by 2 it equals 469 R1
And if you divide 939 by 5 it equals 187 R4

First we get the value of y in terms of x
We have 2x + y + 9 = 0
We transpose 2x and 9 to the other side so we could get the value of y being:
y = - 2x - 9
Now that we have the value of y we can substitute it to the first equation 
6x - 3y + 10 = 0
6x - 3 (-2x - 9) + 10 = 0
Simplifying the inside of the parentheses we would have 
6x - (3)(-2x) - (3)(-9) + 10 =0
6x + 6x + 27 + 10 = 0
Combining similar terms we would get 
12x + 37 = 0
We transpose 37 to the other side for easier simplification 
12x = - 37
We divide both sides by 12 to get the value of x 
12x/12 = - 37/12
Since 12/12 is equal to 1 our value of x would be
x = - 37/12
Or simply x = - 3.0833
Now that we know the value of x we can use it to obtain the value of y
y = - 2x - 9
y = - 2(-37/12) - 9
y = 37/6 - 9
y = - 17/6
Or in decimal y = - 2.8333
Final values of x and y would be
x = - 3.0833
y = - 2.8333
