Its max is 780
2/3 + 1/6 = 5/6
650/5=130
650+130=780
        
             
        
        
        
Answer:
D) 171 cm²
Step-by-step explanation:
You don’t actually need to decompose it.  You could just do it as a trapezoid:
(15+23)/2=19
19x9=171
If you want to decompose it into 2 triangles and a rectangle:
10=15x9=135
1/2(3)(9)=13.5
1/2(5)(9)=22.5
135+13.5+22.5=171 also

3x-4= - 10
add both side 4 so its a addition property 
3x=- 6
now divide both side 3 so it is a  <span>division property.
so x=-2</span>
