Question 86558: 1.A triangle has sides 2x-5, 3x+1 and 4x+2. Find the polynomial that represents its perimeter.
2. Remove the parentheses...
-(3x+5y)
-(4m-3n)
3. Write using exponents and simplify if possible...
(-3x)^-2
4. Add...
5y-4 and 2y^2-8y

You can put this solution on YOUR website!
1) (2X+5)+(3X+1)+(4X+2)=2X+5+3X+1+4X+2=9X+8
2) -(3X+5Y)=-3X-5Y
-(4M-3N)=-4M+3N
3) (-3X)^-2=1/9X^2
4) 5Y-4+2Y^2-8Y=2Y^2-3Y-4
