14) tinggal di kuadratin semua 9pkuadrat - 18 p q kuadrat + 9 q pangkat 4 / 25 r kuadrat ... isiya c
15) (x-2) (x+3) = x.x x2 +x-6 = x2 x -6 = 0 x= 6
maka .... k = 2 (p+l) = 2( (6+3) +( 6-2)) = 2 ( 13) = 26 cm (c)

14) 3 kuadrad . p kuadrad -3 kuadrad . q kuadrad . kuadrad per 5 kuadrad . r kuadrad = 9p kuadrad + 9q pangkat empat per 25r kuadrad (Jawabannya a) 15.L= p x l = s x s = (x+3) x (x-2) = x x x = x kuadrad - 2x + 3x -6 = x kuadrad = x kuadrad + x -6 = x kuadrad = x kuadrad-x kuadrad +x = 6 = x = 6 maka, keliling persegi panjang = 2 (p+l) = 2 ( (x+3) + (x-2) ) = 2 ( (6+3) + (6-2) ) = 2 ( 9 + 4) = 2 (13) = 26 cm (Jawabanya C)
15) (x-2) (x+3) = x.x
x2 +x-6 = x2
x -6 = 0
x= 6
maka ....
k = 2 (p+l)
= 2( (6+3) +( 6-2))
= 2 ( 13)
= 26 cm (c)
= 9p kuadrad + 9q pangkat empat per 25r kuadrad (Jawabannya a)
15.L= p x l = s x s
= (x+3) x (x-2) = x x x
= x kuadrad - 2x + 3x -6 = x kuadrad
= x kuadrad + x -6 = x kuadrad
= x kuadrad-x kuadrad +x = 6
= x = 6
maka, keliling persegi panjang = 2 (p+l)
= 2 ( (x+3) + (x-2) )
= 2 ( (6+3) + (6-2) )
= 2 ( 9 + 4)
= 2 (13)
= 26 cm (Jawabanya C)
