a. 4(p + q) b. 5(ax + by) c. 3(x – 2) + 6(7x + 1) d. –8(2x – y + 3z)

a. 4(p + q)
=4p + 4q

b. 5(ax + by)
=5ax + 5by

c. 3(x – 2) + 6(7x + 1)
=3x - 6 + 42x + 6
=45x

d. –8(2x – y + 3z)
= -16x + 8y - 24z

semoga membantu

jawab :

a) 4(p + q)
= 4p + 4q

b) 5(ax + by)
= 5ax + 5by

c) 3(x-2) + 6(7x+1)
= 3x - 6 + 42x + 6
= 3x + 42x -6+6
= 45x

d) -8(2x-y+3z)
= -16x +8y -24z

semoga membantu......
good luck ^_^
