Question

5r²+3
4r²-6r+1
7r-8
What is the perimeter of the triangle of the triangle shown

Answer 1

Answer: First Choice. 9r² + r -4

Explanation:

Given information

Side 1 = 5r²+3

Side 2 = 4r²-6r+1

Side 3 = 7r-8

Formula for the perimeter of the triangle

Perimeter = Side 1 + Side 2 + Side 3

Substitute values into the formula

Perimeter = (5r² + 3) + (4r² - 6r + 1) + (7r - 8)

Simplify the expression

Perimeter = 5r² + 4r² + 7r - 6r + 3 + 1 - 8

Perimeter = 9r² + r + 4 - 8

Perimeter =
`\Large\boxed{9r^2+r-4}`

Hope this helps!! :)
