Question

Tlng bantu kerjain yaa

Answer 1

1.) 5x - 8 = 3x + 12
5x - 3x = 12 + 8
2x = 20
x = 10

x+3 = 10+3 = 13 (A.)

2.) Kell = 2 (p+l)
52 = 2 (3x-5+x+3)
52 = 2 (4x - 2)
52 = 8x - 4
52 + 4 = 8x
56 = 8x
x = 7

P = 3x-5 = 3(7)-5 = 16 cm
l = x + 3 = 7 + 3 = 10 cm (D.)

3.) P = {b,a,t,i,k}
Himpunan Bagian = 2^n = 2^5 = 32 (A.)

4.) Lomba menulis cerpen = 40 - 23 = 17 + 12 = 29 (C.)

semoga membantu(:
