Is this correct??
Please help.How do I find the length of x?
Since the area of B is 9 times the area of A, we know that the sides of B are √9= 3 times the length of the sides of A.
That's how.
Simplify (4+2i)(4-2i)
A. 20
B. 12
C. 16-4i
D. 16+4i
[tex](a+b)(a-b)=a^2-b^2\\\\(4+2i)(4-2i)=4^2-(2i)^2=\boxed{16-4i^2}[/tex]
Answer:
A
Step-by-step explanation:
We want to simplify the expression:
[tex](4 + 2i)(4- 2i)[/tex]
Notice that this is the difference of two squares. That is:
[tex](a +b)(a-b) = a^2 - b^2[/tex]
We can let a = 4 and b = 2i. Hence:
[tex](4+2i)(4-2i) = (4)^2 - (2i)^2[/tex]
Simplify:
[tex]= (16) - (4i^2) \\ \\ = 16 - (-4) \\ \\ = 20[/tex]
(Note that i² = -1.)
In conclusion, our answer is A.

the hcf of 90 and x is 18. the lcm of 90 and x is 540. find the value of x.
The value of x is 108.
What is HCF?The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that the HCF of 90 and x is 18.
And the LCM of 90 and x is 540.
We have to determine the value of x.
Since the product of two numbers equals the product of their HCF and LCM.
So 90 × x= HCF × LCM
Substitute the values of given data,
⇒ 90×x = 18×540
⇒ 90×x = 9720
⇒ x = 9720/90
⇒ x = 108
Hence, the value of x is 108.

What are the coordinates of the midpoint at (-3,9) and (10,18)
Answer:
(7/2, 27/2) or (3.5, 13.5)
Step-by-step explanation:
The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints.
The y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.
x-coordinate of the midpoint:
(-3 + 10)/2 = 7/2
y-coordinate of the midpoint:
(9 + 8)/2 = 27/2
Answer: (7/2, 27/2) or (3.5, 13.5)
