Question

the legs of a scalene triangle are represented by (x+4),(x+8), and (2x - 3) which polynomial expression best represents the perimeter of the triangle

Answer 1

perimeter means add the side

(x+4) +( x+8)+(2x-3) =P

x+x+2x+4+8-3=P

4x-9 =P

Answer 2

Answer:

$(4x+9)$

Step-by-step explanation:

we know that

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

therefore

$P=(x+4)+(x+8)+(2x-3)\\ \\P=(x+x+2x)+(4+8-3)\\ \\P=(4x+9)\ units$
