Maaf,soal yang anda buat itu salah
jika saya menjawab soal di atas tidak masuk akal.contoh membuat soal:
diketahui,w ={kumpulan huruf pembentuk kata batal}.tentukan banyaknya himpunan bagian w yang memiliki 2 anggota
Penyelesaian
w=b,a,t,l=4
:4!/(4-2)!×2!
4×3×2!/2!×2×1

Answer:
Step-by-step explanation:
- 8x+ 8 = 0
we divide the coefficient of the X by half :
in this case: 8x/2 = 4 , then we do the following
to the result obtained (4) squared: 4^2=16
we sum and subtract by 16 to maintain the balance of equation:
- 8x+ 16-16+8 = 0
we have:
-16 +8=0
=16-8
= 8
we write the square root on both sides of the equation:
we know:
so we have:
abs(x-4)=
abs(x-4)=2
we have:
finally we have:
Answer:
8%
Step-by-step explanation:
27 - 25 = 2
2/25 x 100 = 8%
8% increase
answer is 8%
