Answer:
The Radius is 7.5, the Diameter is 15, as you are just doubling the Radius
Step-by-step explanation:
The correct answer for this question is 11 - 13i.
This is how to answer this one:
(7 - 3i) (2 - i)
= [ (7*2) - (3i*2) - (7*i) + (3i*i) ]
Get the product of each term
= (14 -6i - 7i + 3i^2)
Group similar terms
= 14 - 13i - 3
Simplify.
= 11 - 13i
Side solution:
i = square root (-1)
i^2 = -1
Answer:
One third.
Step-by-step explanation:
Common ratio = 9/27 = 1/3
3/9 = 1/3
1/3 = -/3.
radical
√7(√14 +3√7)
using distributive property,
√7√14 +3√7√7
we can write √14 as √2*√7,
√7√2√7 +3√7√7
√7(√14 +3√7)=7√2 +21
