Somebody please help me with this! The perimeter of an equilateral triangle is represented by the expression 9x + 15. Write an expression the represent the length of ONE side of the triangle.
Write two more equivalent expressions to represent the perimeter of the triangle and explain why they're equivalent.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

the correct answer is c
