5(x+4)=-15
Distribute
5x+20=-15
Subtract 20 from both sides
5x=-35
Divide both sides by 5
x=-7
Final answer: The number is -7
Answer:
15
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
z=119+120 i
Let 
Squaring both sides

Comparing real and imaginary part
Re(LHS)=Re(RHS)
-----------1
comparing Im(LHS)=Im(RHS)
120=2pq

Substitute q in 1


Let 



we take only Positive value because 
x=149.85

thus 

thus
