Question

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 12 more than four times the length of the bottom of the triangle. The last side is 10 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.

Answer 1

ANSWER
Perimeter = 62 + 15
Step-by-step 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 units.
From the diagram perimeter
4 + 12+ ∞ + 3+2 = 6: + 15
Four times the length of the bottom will be 4r
12 more than 4 times the bottom will be 47 + 12
Hence another side of the triangle is 4 + 12
