Question

6. The perimeter of a triangle is 4x - 9. One of the sides is 2x - 3 and another is x + 5. Find the third side​

Answer 1

$\huge\star\underline\mathfrak\green{Answer:-}$

Perimeter is sum of three sides.

3x-5+2x-3+x+3 = 25

=> 6x -5 = 25

=> 6x = 30

=> X = 5

Three sides are :

15–5=10, 10–3=7, 5+3=8

Smallest side is 7

Note :

One has to be careful while attempting such questions as many students stop after calculating value of x.

The question is not asking for value of x, but is asking for smallest side.

Answer 2

$\huge\underbrace\mathfrak \red{ANSWER }.$

Perimeter is sum of three sides.

3x-5+2x-3+x+3 = 25

=> 6x -5 = 25

=> 6x = 30
