Question

1. write the perimeter of the triangle as a simplified expression.

3y + 5
6y
y - 4

Explanation:

Step1: Recall perimeter formula

Perimeter of a triangle is the sum of its three sides. So we add the three expressions: \((3y + 5)+(6y)+(y - 4)\)

Step2: Combine like terms

First, combine the \(y\)-terms: \(3y+6y + y=10y\)
Then, combine the constant terms: \(5-4 = 1\)

Step3: Form the simplified expression

Put the combined terms together: \(10y+1\)

Answer:

\(10y + 1\)
