Multiply both numerator and denominator with 8+5i. Then you get \frac{10(8+5i)}{8 ^{2} +5^{2} } = \frac{80+50i}{89} = \frac{80}{89}+ \frac{50}{89}  i

Which expression shows the result of applying the distributive property to 3(2x−6)3(2x−6) ?
bazaltina [42]
If you are distributing 3(2x-6) then you would do it this way: 
(3 x 2x)(3 x (-6)) 
(6x) (-18)
6x-18 (you can simplify this by dividing by 6)
x-6 would be your answer but I don't see it as one of the options. Are all of these options typed out correctly?

If twice a number is at least three less than four times the number, which of the following are true? Let n represent the number
NikAS [45]

Answer:


Step-by-step explanation:

Let n represent the number

Twice the number =2n


4 times the number = 4n


Given that twice the number is atleast 3 less than four times the number


Algebraically this can be written as


2n≤4n-3


We can add 3 to both sides


So n should be atleast 1.5


If n is natural number or integer then least value of n is 2.

Solve the equation ( 1 point) 3/4x=9<br><br> A) X=12<br> B) X=108<br> C) X=72<br> D) X= 4/9
Elena L [17]

Answer:

x = 12

Step-by-step explanation:

Solve for x:

(3 x)/4 = 9

Multiply both sides of (3 x)/4 = 9 by 4/3:

(4×3 x)/(3×4) = 4/3×9

4/3×3/4 = (4×3)/(3×4):

(4×3)/(3×4) x = 4/3×9

4/3×9 = (4×9)/3:

(4×3 x)/(3×4) = (4×9)/3

(4×3 x)/(3×4) = (3×4)/(3×4)×x = x:

x = (4×9)/3

9/3 = (3×3)/3 = 3:

x = 4×3

4×3 = 12:

Answer:  x = 12
