Question

aflati valoarea expresiei:a)4x+16,pentru x=35, b)12(a+b),pentru a=34, b=56,
c)80-2a,pentru a=27
d)3x-9y,pentru x=208, y=52

Answer 1

a) 4*35+16 = 140+16=156
b) 12(34+56) = 12* 90 = 1080
c) 80-2*27 = 80-54 = 26
d) 3*208 - 9*52 = 624- 468 = 156

Answer 2

a) 4x+16= 4·35+16=156
b)12(a+b)=12(34+56)=1080
c)80-2a=80-2·27=26
d)3x-9y=3·208-9·52=624-468=156
