Bonjour,

a. 2a + 5c

b. ad + 40

c. 38 * (3 + 2c)

= 38 * 3 + 38 * 2c

= 114 + 76c

d. 3z - 0 * h

= 3z

e. 21 - dh

f. 11a - t

g. a * (3 * 9 + b * n)

= a * (27 + bn)

= a * 27 + a * bn

= 27a + abn

Bonjour,

Simplifier :

A. 2×a+5×c = 2a+5c

B. a×d+5×8 = ad+40

C. 38(3+2×c) = 114+76c

D. 3×z-0×b = 3z

E. 3×7-d×b = 21-bd

F. a×11-1×t = 11a-t

G. a×(3×9+b×n) = 27a+abn

Bonne journée.
