Answer:

(x + 2) (5x + 3)(5x - 3)

Step-by-step explanation:

$25x^2(x+2)-9(x+2) \\ \\ = (x + 2)(25 {x}^{2} - 9) \\ \\ = (x + 2) \{ ({5x})^{2} - {(3)}^{2} \} \\ \\ = (x + 2) \{(5x + 3)(5x - 3) \}\\ \\ = \purple{ \bold{(x + 2) (5x + 3)(5x - 3) }} \\ are \: the \: required \: factors$

Answer:

Slope of PV = -4

Step-by-step explanation:

Coordinates of the vertices of the given triangle PSV,

P → (2, 4)

S → (3, 4)

V → (3, 0)

Slope of the segment between two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

Therefore, slope of segment PV will be,

Slope = $\frac{4-0}{2-3}$

= -4

Slope of PV = -4

Given: ΔABC ≅ ΔFDE. . What is the length of segment DE rounded to the nearest tenth?. . 3.2. . 4.2. . 2.2. . 3.6. .

Rus_ich [418]

$d= \sqrt{(3-2)^2 + (1-4)^2 }$
$d= \sqrt{( x_{2}- x_{1})^2 + ( y_{2}- y_{1})^2 } 
$
$d= \sqrt{(1)^2 + (-3)^2 }$
$d= \sqrt{1+9 }$
$d= \sqrt{10 }$
$d= 3.2$
The length of segment DE is 3.2
