Please Help Me!! Its for tomorrow and i rlly need help pls pls pls pls

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 triangle is x. Another side is 9 more than four times the length of the bottom of the triangle. The last side is 11 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.

What is the expression for the perimeter of the​ triangle?

Answer 1

I think the peremeter is 6x+15

Explanation:

Answer 2

perimeter = 6x + 15

Explanation:

The perimeter of the triangle is the distance around the triangle.

We need to apply our ability to convert word problems in to mathematical expressions.

We were told that the bottom of the triangle is x units.

From the diagram perimeter 4x + 12 + x + 3 + x = 6x + 15

Four times the length of the bottom will be 4x .

12 more than 4 times the bottom will be 4x + 12.

Hence another side of the triangle is 4x + 12.

Finally we were told that the last side is 3 more than the bottom, that will be x + 3.
