You can put this solution on YOUR website! a triangle has 3 sides 3x^7 and 4x^9 and 5x+6 find the expressions that represents this perimiter (If the 7 and 9 are not exponents, let me know)
Perimeter is found by adding the sides together: Since there are no like terms, the best you can do is put the terms in descending order.
Happy Calculating!!!
