Bonjour

a. x = 5

A = (5 + x) / 8

A = (5 + 5) / 8

A = 10/8

B = 5 / (x + 3)

B = 5 / (5 + 3)

B = 5/8

A > B

b. x = 3

A = (5 + x) / 8

A = (5 + 3) / 8

A = 8/8 = 1 = 6/6

B = 5 / (x + 3)

B = 5 / (3 + 3)

B = 5/6

A > B

c. x = 0

A = (5 + x) / 8

A = (5 + 0) / 8

A= 5/8 = 15/24

B = 5 / (x + 3)

B = 5 / (0 + 3)

B = 5/3 = 40/24

A < B

d. x = - 2

A = (5 + x) / 8

A = (5 - 2) / 8

A = 3/8

B = 5 / (x + 3)

B = 5 / (- 2 + 3)

B = 5/1 = 5 = 40/8

A < B

e. x = - 11

A = (5 + x) / 8

A= (5 - 11) / 8

A = - 6/8

B = 5 / (x + 3)

B = 5 / (- 11 + 3)

B = - 5/8

A < B

f. x = - 9

A = (5 + x) / 8

A = (5 - 9) / 8

A = - 4/8 = - 12/24

B = 5 / (x + 3)

B = 5 / (- 9 + 3)

B = - 5/6 = - 20/24

A > B.
