An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triang
le is X. Another side is 6 more than three times the length of the bottom of the triangle. The last side is 4 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.
Step-by-step explanation: the base is x. One side is 6 + 3x. The last side is 4 + x. Now add them together 6 + 3x + 4 + x + x. Then simplify to 10 + 5x.
