Question

sper sa fie clară poza. imi trebuie urgent, dau coroana!

Answer 1

1)25*4-75/3/(4+1)=100-15/5=100-3=97
2)MUN={1,2,3,4,5,6,7,8,9}
4)A=L*l=$3 \sqrt{2} * \sqrt{8} =3 \sqrt{16}=3*4=12$m
5) 90

Answer 2

100-25:5=100-5=95
M reunit N={1,2,3,4,5,6,8,9}
a(b-c)=8/3=>a=1
b-c=2,(6)= 2 6/9=2 2/3=8/3

L=3rad2m,l=rad8=2rad2
A=Lxl=3rad2x2rad2=12m^2

m(AD,CC')=m(AD,DD')=M(ADD')=90grade
