Answer:

[tex]P=(6x^2+12x-1)\ in[/tex]

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides (legs) and two equal interior angles

The perimeter of triangle is equal to  the sum of its three length sides

so

[tex]P=2(3x^2+4x+2)+(4x-5)[/tex] ----> remember that the two legs are equal

Eliminate parenthesis

[tex]P=6x^2+8x+4+4x-5[/tex]

Combine like terms

[tex]P=(6x^2+12x-1)\ in[/tex]
