(2+i)^3=(i+2)^3 ↝ Properties

(x+y)^3=x^3+3x^2y+3xy^2+y^3\\(i+2)^3=i^3+3(i)^2(2)+3(i)(2)^2+2^3\\(i+2)^3=i^3+6i^2+12i+8

Proceed with define of complex number.

i=\sqrt{-1}\\i^2=-1\\i^3=-i\\i^4=1

-i-6+12i+8\\2+11i

Therefore, the answer is 2 + 11i

One eighth of a number is ten less than one third of the number. Find the number.
GarryVolchara [31]
X/8 - 10 = x/3

bring the values with the variable on one side

x/3 - x/8 = 10

find a common denominator and subtract these fractions

8x/24 - 3x/24 = -10

now subtract fractions

8x - 3x = 5x

5x/24 = -10

multiply both sides by 24

5x = -240

divide both sides by 5

x = -48

the number is -48

Two interior angles in a triangle measure 101 degrees and 34 degrees. What is the measure of the third angle?
Colt1911 [192]
All the angles in a triangle equal 180 degrees.

So,

101+34+x=180

x= the missing angle.

135+x=180

Subtract both sides by 135.

x= 45

The missing angle equals 45 degrees.

I hope this helps!

Solve y-12/25=3 1/5. What number is y?<br><br> A. 3 1/5<br> B. 3 17/25<br> C. 3 7/25<br> D. 4 17/25
kicyunya [14]

Answer:

Option c) y=3\frac{17}{25} is correct

The value of y is 3\frac{17}{25}

Step-by-step explanation:

Given equation is  

y-\frac{12}{25}=3\frac{1}{5}

To solve the given equation for y

y-\frac{12}{25}=3\frac{1}{5}

y-\frac{12}{25}=\frac{16}{5}  (converting mixed fraction to normal fraction )

y-\frac{16}{5}=\frac{12}{25}

y-\frac{(16\times 5)+12}{25}  (taking LCM 25 )

=\frac{80+12}{25}  (adding the terms )

y=\frac{92}{25}  (now convert fraction into mixed fraction )

Therefore y=3\frac{17}{25}

Option c) y=3\frac{17}{25} is correct

The value of y is 3\frac{17}{25}
