Answer:
8x³ - 5x² + 8x
Step-by-step explanation:
to solve the perimeter, you need to add all sides of the triangle together.
8x² + x³ + 2x² + 7x³ - 3x² + 6x
now, code all the similar variables:
8x² + x³ + 2x + 7x³ - 3x² + 6x
8x² - 3x² = 5x²
x³ + 7x³ = 8x³
2x + 6x = 8x
so, put them all together:
5x² + 8x³ + 8x
but remember that the larger exponent comes first(just a rule)
so, it is : 8x³ - 5x² + 8x
