Oblicz wartosc: a)3-z dla z=-3 b)(x+1)2 dla x= -1,7 c)+(2-t)dla + =1/2 d)6*s-14 dla s 5/6 Prosze o szybka odpowiedz:))
a) 3--3=3+3=6 minus i minus daje plus
b)(x+1)2=(-1.7+1)2=-0.7x2=-1.4
c)2-1/2=1,1/2
d)6*s-14=6*5/6-14=5-14=9
a) 3--3=6
b) (1.7 +1)*2= 2.7 * 2=5.4
c)2-1/2=1.1/2
d) 6*5/6-14= 5-14= -9
