Factor completely 3x 2 + 2xy - y 2

sergij07 [2.7K]

Answer:

Final answer is $(3x-y)(x+y)$ .

Step-by-step explanation:

Given expression is $3x^2+2xy-y^2$ .

Now we need to factor the given expression $3x^2+2xy-y^2$ completely. Let's use factor by grouping method.

$3x^2+2xy-y^2$

$=3x^2+3xy-xy-y^2$

$=3x(x+y)-y(x+y)$

$=(3x-y)(x+y)$

Hence final answer is $(3x-y)(x+y)$ .

Solve the matrix equation below. What is the value of x in the new matrix?

andrew11 [14]

The new matrix that is formed by the 3A + B is given below. Then the value of x is 102.

$\begin{bmatrix} w & z \\y & z \\\end{bmatrix} = \begin{bmatrix} 46 & 102 \\15 & -2 \\\end{bmatrix}$

<h3>What is the matrix?</h3>

A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The $a_{ij }$ element in a matrix, such as M, refers to the i-th row and j-th column element.

The matrices are given below.

$\rm A = \begin{bmatrix}9 & 27 \\0 & 6 \\\end{bmatrix}\\\\\\B = \begin{bmatrix}19 & 21 \\15 & -20\\\end{bmatrix}$

Then the new matrix is given as 3A + B. Then we have

$\rm 3A + B =\begin{bmatrix} w & z \\y & z \\\end{bmatrix}\\\\\\3A + B =3 \times \begin{bmatrix}9 & 27 \\0 & 6 \\\end{bmatrix} + \begin{bmatrix}19 & 21 \\15 & -20\\\end{bmatrix}\\\\\\3A + B = \begin{bmatrix}27& 81\\0 & 18\\\end{bmatrix} + \begin{bmatrix}19 & 21 \\15 & -20\\\end{bmatrix}\\\\\\3A + B = \begin{bmatrix} 46 & 102 \\15 & -2 \\\end{bmatrix}$

A circular hedge surrounds a sculpture on a square base. The radius of the hedge is 6x. The side length of the square sculpture

andrey2020 [161]

Hi, thank you for posting your question here at Brainly.

Since the hedge is surrounding the square base, the area of the base can be determined by subtracting the area of the base from the hedge.

A = pi*r^2 - (4x)^2
A = pi*(6x)^2 - (4x)^2
A = 2x^2*(3pi - 2)

I hope I was able to answer your question. Have a good day.
