Answer 1

Verified answer

Jawaban:
(a.) = 48
(b.) = -8
(c.) = 8
(d.) = -18
-----------------------------
Cara penyelesaian:
Diketahui, k = -6, L = -8, m = -4
Ditanya
hasil kali dua bilangan negatif = positif
(a.) k×L = -6×(-8) = +(6×8) = 48
hasil jika dikali satu bilangan negatif = negatif
(b.) 2m = 2×(-4) = -(2×4) = -8
utamakan perkalian, lalu penjumlahan
(c.) m×(-k)+2L = [-4×(-6)]+[(2×(-8))] = 24-16 = 8
(d.) k+L+m = -6+(-8)+(-4) = -(6+8+4) = -18

Answer 2

Jawaban:

a. k × L = (-6) × (-8) = 48

b. 2m = 2(-4) = -8

c. m × (-k) + 2L = (-4) × (-6) + 2(-8) = 24 - 16 = 8

d. k + L + m = (-6) + (-8) + (-4) = -18
