no 24 sama 25 yg jwban bener dikasih tambahan poin

24. misal bilangan kedua = x
mka bilang prtama = x + 5
x(x+5) = 300
x² + 5x = 300
x² + 5x - 300 = 0
x² + 20x - 15x - 300 = 0
(x-15)(x+20)=0
x1 = 15
x2 = -20
*x = 15 (positif)
jumlah kedua bilangan
= x + (x+5)
= 35

25. s = sisi persegi
(s+3)(s+5) = 3s²+5
s²+8s+15 = 3s²+5
0 = 2s²-8s-10
0 = s²-4s-5
0 = (s+1)(s-5)
s1 = -1, s2 = 5
s = 5 (positif)
(s+3)(s+5) = 80
