The perimeter of a triangle is 14x−4. If two sides measure 3x−2 and 5x+3, then how long is the third side?

To earn full credit, show your work ( omg please put explanation plsss )

Sagot :

Perimeter of a triangle = Length of the first side + Length of the second side + Length of the third side

( 14x – 4 ) = (3x-2) + ( 5x +3) + Length of the third side

14x – 4 = ( 8x +1 ) +Length of the third side

(14x-4) + (-8x-1) =Length of the third side

6x - 5 = Length of the third side

So; The length of the third side = 6x – 5

I hope I helped you^_^

Answer:

6x-5

Step-by-step explanation:

A triangle has 3 sides; the perimeter= a+b+c

P= 14x-4

a= 3x-2

b= 5x+3

c=?

14x-4 = (3x-2) + (5x+3) + c

14x-4= 3x-2+5x+3+c

Put alike terms together

14x-4= 3x+5x-2+3+c

14x-4= 8x+1+c

Make c the subject of the formula

c= 14x-4-8x-1

c= 14x-8x-4-1

c= 6x-5
