The unknown number is 48 using the equation: x ÷ 12 +49=53 subtract 49 from both sides and get x ÷ 12 = 4 multiplying by 12 on both side to get rid of the ÷12 and get the final answer of x=48.
The domain of F(x) is all real numbers.
This is due to the fact that the function has no undefined points or domain constraints.
The next step in the equation is the quotient
3x+15^2+10= -2
3x+225+10= -2
3x+235= -2
Divide both sides by 3
x+235=0.67
Subtract 235 from both sides
x= -234.33
Sorry, in advance, if I did it wrong.
5^2+(-2)^2=29
magnitude=(29)^(1/2)=around 5.3852
