Question

find the perimeter of an equilateral triangle having each side of (7x²+8xy-2).​

Answer 1

Answer:

21x² + 24xy - 6

Explanation:

Perimeter of an equilateral triangle is given by,

→ 3 × each side.

Then,

→ 3(7x² + 8xy - 2)

→ 3(7x²) + 3(8xy) - 3(2)

→ 21x² + 24xy - 6

Requires answer: 21x² + 24xy - 6
