The legs if an isosceles triangle are (3x^2+4x+2) inches and the base is (4x-5) inches. Find the perimeter of the triangle
alexdok [17]

Answer:

P=(6x^2+12x-1)\ in

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

so

The perimeter of triangle is equal to

P=2(3x^2+4x+2)+(4x-5)

Eliminate parenthesis

P=6x^2+8x+4+4x-5

Combine like terms

P=(6x^2+12x-1)\ in
