Step-by-step explanation:

2,

(a.y^{3} +3y^{2} -3 ) = (ay^{2} +(4a+3)y +4(4a+3))(y-4) +64a+45

so A = 64a +45

(2y^{3} -5y+a =(2y^{2} +8y +27)(y-4) +108 +a

so B = 108 +a

2A-B=0--> 2(64a+45)-108-a=0--> a =18/127

3,

(3x+2y)^3 = 27x^3 +54x^2.y + 36x.y^2 +8y^3 = 27x^3 +8y^3 +2 +18xy(3x +2y) = 20^3

so P = 27x^3 +8y^3 = 20^3 - 18.xy(3x+2y)= 7440

The Perimeter of a rectangle is 36. If there's 5n + 3 and 1/4n + 2, what's the value of n?
seropon [69]
Perimeter: 36

5n + 3 = 36
5 · 6.6 + 3 = 36

N = 6.6
------------------------------------------
Perimeter: 36

1/4n + 2 = 36
1/4 · 136 + 2 = 36

N = 136

Hopefully i understood the question correctly :) Hope this helps

Teagan is dividing 6 by 11. If she continues the process, what will keep repeating in the quotient? The sequence 05 Only the dig
Oksi-84 [34.3K]

Answer:

Teagan is dividing 6 by 11. If she continues the process, what will keep repeating in the quotient?

The sequence 05

Only the digit 5

The sequence 54

Only the digit 4

The sequence 54  is the final answer.

Step-by-step explanation:

Given:

A a fraction 6/11 which Teagan is dividing we have to find the repeating quotient.

Here the divisor is 11 and the dividend is 6.

Lets say that the quotient is "q" .

And we know that:

⇒ Dividend / divisor = quotient

Or

In mixed fraction.

⇒ Dividend / divisor = quotient + (remainder/ divisor)

Finding the values of "q".

⇒ \frac{Dividend}{divisor} = quotient

⇒ \frac{6}{11} = 0.5454....

Explanation:

  • To divide 6 with 11 we have to take a decimal in quotient which allows us to have a zero in each step in the quotient.
  • After putting zero the dividend will become 60 and then we can apply 11\times 5 = 55 ...5 in the quotient and 55 in the numerator.
  • In third step we will subtract 55 with 60 that will give us 5 putting a zero with it it will be now 50 ,and the closet multiple of 11 is 11\times 4=44, 4 with the quotient and and 50-44=06 will continue to be divided.
  • The fraction is a rational numbers as the decimals occurring are repeating decimals in the quotient.

Our final answer from the option is : C

The sequence 54 will be repeating.

Y=x+3 y=2x+4 please answer ASAP
Angelina_Jolie [31]
You don't share the instructions here.  Guessing, it seems that the whole problem was originally stated, 

"Solve the following system of linear equations:"

<span>Y=x+3
y=2x+4

Mult. the first equation by -2:    -2y = -2x - 6
Add the 2nd equation to this:       y = 2x + 4
                                                 -----------------
                                                    -y = -2, so y = 2.

Subst. 2 for y in the first equation:  2=x+3.  Then x = -1.

The solution of this system is (-1, 2).
