For complex number, the magnitude is pretty straight forward:
sqrt(6^2 + 2^2) = sqrt(40)
For any a + bi, the magnitude will be sqrt(a^2 + b^2)
Answer: The number is 15
Step-by-step explanation: basically the equation you should solve is
(x)+(2x)+(2x+7)=82
5x+7=82
5x= -7+82
5x=75
5/5x=75/5
x=15
Answer:
7x² + 9x + 6y
Step-by-step explanation:
7x² + 4x + 5x + 8y - 2y
1200 +29%= (1200+240)=1440
1440-300=1140
1140÷10=114
so the answer is £114 per month for 10 months
