Question

Can someone please help me on this i am having difficulties on it

Answer 1

(2s+4)+(4s+2)+3=6s+9. This can also be rewritten as 3(2s+3).

Answer 2

We know that the perimeter of a triangle is the sum of its three sides.

P= 3+ (2s+4)+ (4s+2)
= (2s+ 4s)+ (3+ 4+ 2) (combine like terms)
= 6s+ 9

The perimeter is 6s+9 (units)~
