Answer:
x=40/9
Step-by-step explanation:
Multiplying complex numbers is a lot like multiplying binomial terms. The only relation one has to remember when dealing with complex numbers is that i² = -1.
Now let us try to multiply binomials. This is done by adding the products of the first term of the first binomial distributed to the second binomial, and the second term of the first binomial distributed to the second binomial. This is done below:
(<span>3 – 5i)(–2 + 4i) = -6 + 12i + 10i -20i²
</span>
Simplifying and applying i²<span> = -1:</span>
-6 + 22i - 20(-1)
-6 + 22i + 20
14 + 22i
Among the choices, the correct answer is B.

Solution:
we have been asked to find
Which length is greater 1/2 meter or 240 centimeters.
To compare the two given lengths, we will have to make both the length in same unit system.
Here 1/2 meter can be written as 50 centimeter , because 1 meter =100cm.
Now its very clear that 240 centimeters is more than 50 centimeters.
Hence we can say 240 centimeters is greater than 1/2 meter .
