−1 + 10i
1 + 6i
1 + 10i
The given expression simplified can be written as -1 + 6i. which is the correct answer that would be an option (A).
A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib,
where a, and b are real numbers and i is an imaginary number.
To simplify the expression (3 + 8i) − (4 + 2i), we need to subtract the two complex numbers. To do this, we subtract the real parts and the imaginary parts separately.
The real part of the first complex number is 3, and the real part of the second complex number is 4.
Subtracting these gives us -1.
The imaginary part of the first complex number is 8, and the imaginary part of the second complex number is 2.
Subtracting these gives us 6. Therefore, the simplified expression is (-1) + (6i) = -1 + 6i.
Therefore, the correct answer is: -1 + 6i.

Answer:
-1+6i
Step-by-step explanation:
(3+8i)-(4+2i)
3+8i-4-2i
3-4+8i-2i
-1+6i
Solve x + x + 2 + 2x = -2.

-2
Answer:
The answer is b: -1
Step-by-step explanation:
x + x + 2 + 2x = -2
Collect like terms
x + x + 2x = -2 - 2
4x = -4
Divide both sides by 4
x = -4/4
x = -1
Answer:
as follows
Step-by-step explanation:
It will take the centipede 36 minutes to travel 1 yard.
It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
We know that there are 36 inches in 1 yard.
The centipede is crawling at a rate of 6 inches per minute.
To find out how long it will take the centipede to travel 1 yard, we can set up a proportion:
6 inches/minute = x minutes/36 inches
where x is the number of minutes it will take the centipede to travel 1 yard.
Now,
6 inches x 36 inches = x minutes
216 inches = x minutes
Now,
216/6 = 36
Thus,
It will take the centipede36 minutes to travel 1 yard.
