n! is called a factorial.

It would look something like this: n! = 1·2·3·...·n

An example:

5! = 1·2·3·4·5 = 120

! means you would do 8*7*6*5*4*3*2*1
or 1*2*3*4*5*6*7*8

25x power square - 36 y power square

finlep [7]

$\implies {\blue {\boxed {\boxed {\purple {\sf { (5x + 6y)(5x - 6y) }}}}}}$

$\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}$

$={25x}^{2} - 36 {y}^{2}$

$= ({5 \times 5)x}^{2} - (6 \times 6){y}^{2}$

$= ({5x})^{2} -( {6y})^{2}$

$= (5x + 6y)(5x - 6y)$

${a}^{2} - {b}^{2} = (a + b)(a - b)$

What is the value of x in the equation 3x-1/9=18 when y equals 27

anygoal [31]

Answer: 163/27

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x + -1/9 = 18

Step 2: Add 1/9 to both sides.

3x + -1/9 + 1/9 + = 18 + 1/9

3x = 163/9

Step 3: Divide both sides by 3.

3x/3 = 163/9 over 3

x = 163/27

Triangle ABC with coordinates A (3,-2), B (5,5), and C (-4, 2) is reflected across

son4ous [18]

Step-by-step explanation:

the formula of coordinates (x, y) that reflected across the x-axis : (x, y) => (x, -y)

so,

A(3, -2) => A'(3, 2)

B(5, 5) => B'(5, -5)

C(-4, 2) => C'(-4, -2)
