Answer 2

no 1

b. 3 x a² x 2 x b x c

no 2
-3x
koefisien = -3

b.-3

no 3
x + 11 = 24
x = 24 - 11
x = 13

c. 13

no 4
16 - x = 7
16 - 7 = x
9 = x

d. 9

no 5
5x + 6y - x + 5y
= 5x - x + 6y + 5y
= 4x + 11y

a. 4x + 11y

no 6
3a - 7b + 2a + 5b
= 3a + 2a - 7b + 5b
= 5a - 2b

d. 5a - 2b

no 7
6p + 8q - (4p - 2q)
= 6p + 8q - 4p + 2q
= 6p - 4p + 8q + 2q
= 2p + 10q

b. 2p + 10q

no 8
a = 3
b = -2
c = 1

2a² + 3bc
= 2.3² + 3.-2.1
= 2.9 - 6
= 18 - 6
= 12

c. 12

no 9
a²bc³
b²c³d
kpk = a²b²c³d

d. a²b²c³d

no 10
p + l
= 2x + 5 + 3x - 2
= 2x + 3x + 5 - 2
= 5x + 3
