6) Simplifier les expressions littéraled suivantes: a) g = 7 × m - 3 b) h = c × c + 5 × c c) k = (8 × s – 5) × (4 - 6 × r) d) m = 7 - d × d + 3 × (5 + d) Merci●

Bonjour

Simplifier les expressions littérales  suivantes :

a) g = 7 × m - 3

g = 7m - 3

b) h = c × c + 5 × c

h = c³ + 5

c) k = (8 × s – 5) × (4 - 6 × r)

k = (8s - 5) (4 - 6r)

k = 32s - 48rs - 20 + 30r

d) m = 7 - d × d + 3 × (5 + d)

m = 7 - d² +  15 + 3d

m = - d² + 3d + 22.
