Question

The lengths of the sides of a triangle are defined by the ff. functions , (x)=2x-3 , S2(x)=x²+3x-5, and s,(x)=4x+4. what is the perimeter of the triangle?​

Answer 1

Answer:

Since the perimeter is given as 25, we can just add the given sides to get 25.

(3x-5)+(2x-3)+(x+3)=6x-5=25

Hence 6x=25+5=30 which gives x=30/6=5

So the sides are (3x-5)=(3*5)-5=10

(2x-3)=(2*5)-3=7 and (x+3)=5+3=8

So the length of the smallest side is 7 units.
