Question

Mohon pencerahannya ya guys

Answer 1

P(3x + 2) = P(5)

3x + 2 = 5

3x = 3

x = 3/3

x = 1

P(5) = x

P(5) = 1

Q(6 - 2x) = Q(4)

6 - 2x = 4

-2x = -2

x = 1

Q(4) = 4x

Q(4) = 4(1)

Q(4) = 4

P(3x + 2) = P(4)

3x + 2 = 4

3x = 2

x = 2/3

P(4) = 2/3

P(3x + 2) = P(5)

3x + 2 = 5

x = 3/3

x = 1

P(5) = x

P(5) = 1

Q(6 - 2x) = Q(1)

6 - 2x = 1

-2x = -5

x = 5/2

Q(1) = 4x

Q(1) = 4(5/2)

Q(1) = 2(5)

Q(1) = 10

P(Q(4) = P(4) = 2/3

Q(P(5) = Q(1) = 10

3(P(Q(4)) + Q(P(5))) = 3(2/3 + 10) = 3(2/3 + 30/3) = 3(32/3) = 32.

c. 32.
