Answer:
80 + 18i
Step-by-step explanation:
i² = -1
x = i + 9
x² = (i + 9)²
Applying; (a + b)² = a² + 2ab + b² concept,
x² = i² + 18i + 81
We know that i² = -1
So x² = -1 + 18i + 81
x² = 81 - 1 + 18i = 80 + 18i
Answer:
Yes, it doubles.
Step-by-step explanation:
2 times 8.6 is 17.2
it doubles because of the ratio the sides of a rite triangle are in. the ratio is always the same
Your radius would have to be 1.91
So 200 - 170 = 30 , 30 is 17.6470588235% so the answer would be B)18%
