Question

The perimeter of triangle is (17x - 3)cm. If it's two sides are (2x - 5)cm and (7x +4)cm. What is the length of it's third side?

Answer 1

Answer:

8x - 2 is the third side

Step-by-step explanation:

perimeter of triangle = side¹ + side² + side³

( 17x - 3 ) = ( 2x - 5 ) + ( 7x + 4 ) + side³

( 17x - 3 ) = 9x - 5 + 4 + side³

17x - 3 = 9x - 1 + side³

17x - 9x - 3 + 1 = side³

8x - 2 = side³

Answer 2

Answer:

bla bla i the answer

Step-by-step explanation:

i can give you the hint

sum of two side - the perimeter

(2x-5)+(7x+4)

(9x-1)-(17x-3)

9x-1-17x+3

-8x+2

-8x=-2

8x=2

x=2/8

x=1/4
