Answer:
36 units
Step-by-step explanation:
We have
(a + b)² = a² + 2ab + b²
so that with a = x² and b = 5, we have
x⁴ + 10x² + 25 = (x² + 5)²
Next, we have
a² - b² = (a - b) (a + b)
so that with a = x and b = √5 i,
x² + 5 = x² - (-5) = (x - √5 i) (x + √5 i)
So, the complete factorization over the complexes is
(x - √5 i)² (x + √5 i)²
To work out 7% of 600, this is what you do
7/100 x 600
this will give you your answer
7% of 600 = 42
7. -8/3
8. 4/35
9. -21/50
10. 35/64
11.-25/54
Answer:
