Answer:

[tex]8-6i[/tex]

Step-by-step explanation:

Multiply out [tex](3-i)^2[/tex] in order to find out which expression it is equivalent to.

1) Since the whole quantity is squared, write it out as [tex](3-i)(3-i)[/tex].

[tex](3-i)^2\\(3-i)(3-i)[/tex]

2) Multiply binomials by using the FOIL method. Multiply the terms that are listed first in each binomial, then the ones that are listed outermost when looking at both binomials, then innermost, and finally the last terms listed in each binomial. Simplify and combine like terms.

[tex](3-i)(3-i)\\9 - 3i - 3i + i^2[/tex]

[tex]9 - 6i + i^2[/tex]

3)  [tex]i = \sqrt{-1}[/tex], so [tex]i ^2[/tex] must be [tex](\sqrt{-1} )(\sqrt{-1})[/tex]. Thus, [tex]i^2[/tex] is equivalent to -1. Knowing this, simplify and combine like terms.

[tex]9 - 6i + ((-\sqrt{1} )(\sqrt{-1} ))[/tex]

[tex]9 - 6i -1\\8 - 6i[/tex]

Thus, it is equivalent to  [tex]8 - 6i[/tex] .

Answer:

x = 3 i promise that's the right answer

Step-by-step explanation:

Answer:

x=3

Step-by-step explanation:

Step #1. Simplify what you've been given

5x-3-2x=18-4x

5x-2x=3x

3x-3=18-4x

Step #2. Add 4x to both sides

3x+4x-3=18

7x-3=18

Step #3. Add 3 to both sides

7x=18+3

7x=21

Step #4. Divide both sides by 7

x=21/7

x=3

Answer:

The probability that the counter  was blue is [tex]\mathbf{\frac{2}{5}}[/tex]

Step-by-step explanation:

Number of black Counters = 5

Number of blue Counters = 4

Number of white Counters = 1

We need to write down the probability that the counter  was blue.​

First find Total Counters

Total Counters = Number of black Counters + Number of blue Counters + Number of white Counters

Total Counters = 5+4+1

Total Counters = 10

Now, we need to find probability that the counter taken was blue

The formula used is:

[tex]Probability= \frac{Number\:of\:favourable\:outcomes}{Total\:outcomes}[/tex]

There are 4 blue counters in the back, so Favourable outcomes = 4

[tex]Probability= \frac{Number\:of\:favourable\:outcomes}{Total\:outcomes}\\Probability= \frac{4}{10}\\Probability= \frac{2}{5}[/tex]

The probability that the counter  was blue is [tex]\mathbf{\frac{2}{5}}[/tex]

Step-by-step explanation:

Answer:

x=9

Let's solve your equation step-by-step

12(x−2)+3x=x+12+10x

Step 1: Simplify both sides of the equation.

12(x−2)+3x=x+12+10x

(12)(x)+(12)(−2)+3x=x+12+10x(Distribute)

12x+−24+3x=x+12+10x

(12x+3x)+(−24)=(x+10x)+(12)(Combine Like Terms)

15x+−24=11x+12

15x−24=11x+12

Step 2: Subtract 11x from both sides.

15x−24−11x=11x+12−11x

4x−24=12

Step 3: Add 24 to both sides.

4x−24+24=12+24

4x=36

Step 4: Divide both sides by 4.

4x/4=36/4

x=9

Answer:

x=9

Answer: x = 9

Step-by-step explanation:

12(x − 2) + 3x = x + 12 + 10x

12(x - 2) + 3x = 11x + 12

12x - 24 + 3x = 11x + 12

15x - 24 = 11x + 12

15x = 11x + 12 + 24

15x = 11x + 36

15x - 11x = 36

4x = 36

x = 36/4

x = 9

Answer:

7.2 X 2000 = 14400 pounds

5/8 = 0.625, 0.625 X 2000 = 1250 pounds

14400 + 1250 + 8500 = 24150 pounds

24150/2000 = 12.08 tons

Answer:

Answer:

$2.02

Step-by-step explanation:

1.50/2 = 0.75

0.75 - 0.49 = 0.26

Sandwich = 2(0.75)+1.5 = 3

Drink = (0.49) + 0.49 = 0.98

3 - 0.98 = 2.02

Answer:

y = -5x - 5

Step-by-step explanation:

to get the coefficient of the 'x' term (which is the slope) you take the difference of the y-values [5 - (-5)] divided by the difference of the x-values  (-2 - 0)

so slope = 10/-2 or -5/1

to get the -5, this is the point at which the line intersects the y-axis; from looking at the graph you can see this is -5

Answer:

156°

Step-by-step explanation:

Reason 1.

M∠A + m∠B + m∠C = 1.

2.

28° + x − 4° + = 180°

We collect like terms

x = 180° + 4° - 28°

x = 156°

Answer:

Bob's dog should be given 216 mg of medicine.

Step-by-step explanation:

Given that:

Weight of dog = 30 lbs

We know that:

1 lb = 0.45 kg

30 lbs = 0.45 * 30 kg

30 lbs = 13.5 kg

Medicine for each kilogram of weight = 16 mg

1 kilogram = 16 mg

13.5 kg = 16 * 13.5 mg

13.5 kg = 216 mg

Hence,

Bob's dog should be given 216 mg of medicine.

Answer:

24x / 5y

Step-by-step explanation:

Given :

24x² / 5xy

24x² = 24 * x * x

5xy = 5 * x * y

Hence,

24x² / 5xy = (24 * x * x) / (5 * x * y)

= (24 * x) / (5 * y)

= 24x / 5y

Answer:

$22,400.

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 14%/100 = 0.14 per year,

then, solving our equation

I = 40000 × 0.14 × 4 = 22400

I = $ 22,400.00

The simple interest accumulated

on a principal of $ 40,000.00

at a rate of 14% per year

for 4 years is $ 22,400.00.
