Answer:
1 and 5. First and the last one
Step-by-step explanation:
i just took the ed test.
Follow PEMDAS.
You would first do your distributive property which is, -5(z+2). You would multiply -5 to z and -5 to 2 which will give you -5z + -10.
so now you have 2z-5z+ -10= -8 - 2z. Now you must isolate the variable. So subtract -8 to -10 which will give you -18.
Now you have the equation 2z-5z-18=-2z
Now combine like terms. 2z-5z= -3z
Now you have the equation -3z-18=-2z
Now you must move the -3z to the other side of the equal sign by adding the opposite which is +3z to -2z which will give you +1z
Now you have -18= 1z
Now you divide. -18 divided by 1 is -18.
So your final answer will be -18=z

Answer:
x is greater than -4
Step-by-step explanation:
Step-by-step explanation:
✧ 
- Set up an equation and solve for x :
⋆
[ Exterior angle is always equal to the sum of two non - adjacent interior angles ]
~Remove the unnecessary brackets
⟶ 
~Add the like terms : 2x ° & 3x°
⟶ 
~Move 4x to right hand side and change it's sign
~Similarly move 12 to left hand side and change it's sign
⟶ 
⟶ 
⟶ 
- Now , Substituting the value of x in (4x+9)° [ Exterior angle ]
