Answer:

Perimeter = 3x + 3

Step-by-step explanation:

Perimeter of the given triangle in the figure is the sum of all three sides.

The expressions for the 3 sides are given as, x, (x - 3), (x + 6).

Therefore,

Perimeter = x + (x - 3) + (x + 6)

Simplify,

Perimeter = x + x - 3 + x + 6

Collect like terms

Perimeter = x + x + x - 3 + 6

Perimeter = 3x + 3

If the graphs of the equations in a system of linear equations coincide with each other, what does that tell you about the solut
salantis [7]
 If by "coincide", in other words this is also known as intersect, it means that the solution to the system is that intersection point. For instance, if the intersection point of the 2 lines is (5,7) on the graph, it means that in both equations, x = 5 and y = 7. If you mean that the 2 equations result in the same line, it means that the 2 equations were really equal, but that one could be basic to be identical with the other. For example, if you have 2x + 2y = 8 and 4x + 4y = 16, they will give you the same line, and you can see that if you divide that second equation by 2 all the way crossways, it merely shows the first equation.
