Question

And this also pls. ​

Answer 1

Answer: hope it helps uhh..

Step-by-step explanation:

since the sides are equal.

∴4x-3=9-2x

4x+2x=9+3

6x=12

x=2

 

so,

Perimeter=3×2+4×2-3+9-2×2=6+5+5=16

Answer 2

since it's an isosceles triangle so the two sides are equal ..... by equating the two sides we can find the value of x

4x-3=9-2x

4x+2x=9+3

6x=12

X=12/6

X=2

first side=4*2-3=5

second side=9-2*2=5

3rd side=3*2 =6

perimeter=5+5+6= 16
