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
