Question

Ajutor!!! Am nevoie de toate 6!!​

Answer 1

1. -2-12= -14

2. 27:9= 3

3. pe 4 il putem scrie ca 2^2

(-2)^12 : (2^2)^5= (-2)^12 : 2^10= (-2)^2= 4

4. x = -16:2

x= -8

5. 5×(-2)+m= -7

-10+m= -7

m= -7+10

m= 3

6. 2x-1=3

2x= 4

x= 2

sau alt caz

2x-1= -3

2x= -2

x= -1

deci varianta este B

Answer 2

1. -14

2. +3

3. -4

4. -8

5. +3

6. (-1;2)
