tolong jwb no 14 dan 15 yh plis!

14. K = 2xP+2xL = 2(3x-2) + 2(5X+3)
= 6X-4 + 10X+6
= 16x+2
15. K = S+S+S
K = (X+5) + (2X+4) + (3X+3)
K= 6X + 12

14. K= p x y
= 2(3x-2) + 2(5x+3)
= (6x+10x)+(-2+3)
= (16x+1)

15. K= s x s x s
= (x+5)+(2x+4)+(3x+4)
= (x+2x+3x)+(5+4+4)
= (6x+13)

Semoga membantu （＾_＾）
