Subtract (3 + 2i) from (–9 – 8i).a. –17 – 5i

b. –6 – 6i

c. –12 – 10i

d. 12 + 10i

Answers

The answer is -12-10i

Given two complex numbers

First complex number = 3+2i ....(1)

Second Complex number = -9-8i..... (2)

Subtracting equation (1) from equation (2)

As this is a subtraction between complex numbers hence the Real part gets subtracted from the real part and the imaginary part gets subtracted from the imaginary part

( -9- 8i ) - ( 3 +2i )

= -9 -3 -8i - 2i

= -12 -10i

55% of what number is 231

Answers

231=100%
2) x=55% that it

55% = 55/100
let 'what number' be x

55% of what number = (55/100) * X which is 231 or

(55/100) * X = 231
x = 231 *(100/55)

If y=2 when x=3. What is the value of y when x=9?

Answers

because x was *3 you had to y*3 which is
y=6

y = 2
x = 3

If x = 9, = x * 3

Thus, y * 3 = 6.

Thus, y = 6.

Use a factor tree to find the prime factorization of 164

Answers

On the first hand, 164 is not a prime number. Prime numbers are numbers that can only be divided by 1 or itself which is also greater than 1 thus;
Prime divisor of 164= 2,2,41 or 2^2 x 41
Here is the factor tree of 164:
164
/     \
2     82
/       \
2      41
Prime factorization of a number determines the set of prime integers multiplied together to make the original number.

Answer:

2 * 2 * 41
