Question

in a triangle, each side = x + 2 and perimeter = 15 units
rectangle, adjacent sides measure x + 2 and 2x - 3 and perimeter = 40 units find its x​

Answer 1

3(x+2) = 15

3x = 9

x = 3

in second case ,

2(x+2+2x-3) = 40

3x-1 = 20

x = 7

Answer 2

Answer: triang

Step-by-step explanation:

triangle have 3 side so

perimeter of triangle = sum of all side

15 units    = x+2 + x+2+ x+2

15 unit = 3x+6

15 - 6   =  3x

9   =   3x

x = 9/3

x = 3 answer
