x=45
200,000 thousand is the answer kid.
Answer:
infinitely many solutions
Step-by-step explanation:
x + 6y = -5
3x + 18y = -15
Multiply the first equation by 3
3(x + 6y) = -5*3
3x + 18y = -15
The two equations are identical. This means they have infinite solutions along the line x+6y = -5
Triangular prism. It has three sides so a triangle
