Factor completely 16x8 − 1.
marta [7]

<u>Given</u>:

The given expression is 16 x^{8}-1

We need to determine the factor of the given expression.

<u>Factor</u>:

Let us rewrite the given expression.

Thus, we have;

\left(4 x^{4}\right)^{2}-1^{2}

Since, the above expression is of the form a^2-b^2, let us apply the identity a^2-b^2=(a+b)(a-b)

Thus, we have;

\left(4 x^{4}+1\right)\left(4 x^{4}-1\right) ------ (1)

Now, we shall factor the term 4x^4-1

4x^4-1=(2x^2)^2-1^2

           =(2x^2+1)(2x^2-1)

Substituting the above expression in equation (1), we have;

\left(4 x^{4}+1\right)\left(2 x^{2}+1\right)(2x^2-1)

Therefore, the factor of the given expression is \left(4 x^{4}+1\right)\left(2 x^{2}+1\right)(2x^2-1)

Hence, Option B is the correct answer.

In a second grade class containing 13 girls and 10 boys, 2 students are selected at random to give out the math papers. what is
Natali5045456 [20]
The fact that the first chosen student was a girl is already decided, so there is no need to find the probability of that happening. There are a total of 13+10, or 23 students. A girl was already selected, so that leaves 22 students. The chance that a boy is chosen is 10/22, or 5/11.

Ralph bought a computer monitor with an area of 384 square inches. The length of the monitor is six times the quantity of five l
Alenkasestr [34]
Draw the picture and label the 
  width = w 
 The length of the monitor is six times the quantity of five less than half its width:
 length = 6(w/2-5)
 length = 3w-30
 Area = (length)*(width)
 384=(3w-30)*(w)
 384=3w^2-30w
 Answer:
 the dimensions of the monitor in terms of its width is: 
 384=3w^2-30w

Find the solution set of the following equations: <br><br>2y=2x+7<br><br>X=y+2
kirill115 [55]

Answer:

The system of equations has no solution.

Step-by-step explanation:

Given the system of equations

2y = 2x+7

x = y+2

solving the system of equations

\begin{bmatrix}2y=2x+7\\ x=y+2\end{bmatrix}

Arrange equation variables for elimination

\begin{bmatrix}2y-2x=7\\ -y+x=2\end{bmatrix}

Multiply -y+x=2 by 2:  -2y+2x=4

\begin{bmatrix}2y-2x=7\\ -2y+2x=4\end{bmatrix}

so adding

-2y+2x=4

+

\underline{2y-2x=7}

0=11

so the system of equations becomes

\begin{bmatrix}2y-2x=7\\ 0=11\end{bmatrix}

0 = 11 is false, therefore the system of equations has no solution.

Thus,

No Solution!
