Question

write a polynomial expression for the perimeter of a triangle whose sides has the following lengths
x+8,3x^2+4x,x^2-3x+6

Answer 1

add them~ tell me what you get

Answer 2

1

Answer 3

how did you get 1? o_o

perimeter = the sum of all sides

x+8 + 3x^2 + 4x + x^2 - 3x + 6 <--- do this again

Answer 4

2(x+7+2x^2)

Answer 5

yup correct
but you should arrange them like this
4x^2 + 2x + 14

Answer 6

ok
