Answer: $11.41
Step-by-step explanation:
X= -3
2/3x-10=12
Step 1: Add 10 to both sides.
2/3x=-2
Step 2: Multiply both sides by 3/2.
x= -3
Well, it depends on the triangle and how big it is, if we dont know, there could be infinite possibilities
If you put the problem on a graph, the graph will show you (2,4)^2 and it'll be in a U-shape.
This probably won't help but let me know. :)
