Find the perimeter of the triangle.

Arturiano [62]

The base is from 2 to 7, which is 5 units long.

The height is from 1 to 8, which is 7 units tall.

Using the Pythagorean theorem we can calculate the hypotenuse:

Hypotenuse = √5^2 +7^2=

√25 +49=

√74=

8.6

Perimeter = 5 + 7 + 8.6 = 20.6

The answer is C.

quadrilateral paid is a rectangle whose diagonals have the endpoints p(-3, -2)i(4, -7) and a(4, -2)d(-3, -7). find the diagonals

julia-pushkina [17]

Answer:

The intersection point of diagonals is (0.5,-4.5).

Step-by-step explanation:

The end points of first diagonal are p(-3, -2) and i(4, -7).

The end points of second diagonal are a(4, -2) and d(-3, -7).

If a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The equation of first diagonal is

$y-(-2)=\frac{-7-(-2)}{4-(-3)}(x-(-3))$

$y+2=\frac{-5}{7}(x+3)$

$7y+14=-5(x+3)$

$7y+14=-5x-15$

$5x+7y=-29$ .... (1)

The equation of second diagonal is

$y-(-2)=\frac{-7-(-2)}{-3-4}(x-4)$

$y+2=\frac{-5}{-7}(x-4)$

$7y+14=5(x-4)$

$7y+14=5x-20$

$5x-7y=34$ .... (2)

Add equation (1) and (2),

$10x=5$

$x=0.5$

Put this value in (1).

$5(0.5)+7y=-29$

$y=-4.5$

The intersection point of diagonals is (0.5,-4.5).

Which statement shows how the product of (x + 7)2 demonstrates the closure property of multiplication?

Illusion [34]

The true statement that show the closure property of multiplication :

<h3>a. x² + 14x + 49 is a polynomial</h3>

$\texttt{ }$

<h3>Further explanation</h3>

<em>If equation ax³ + bx² + cx + d = 0 has roots x₁ , x₂ , and x₃ then</em>

$x_1 + x_2 + x_3 = - \frac{b}{a}$

$x_1 x_2 + x_1 x_3 + x_2 x_3 = \frac{c}{a}$

$x_1 x_2 x_3 = - \frac{d}{a}$

Let us now tackle the problem!

$\texttt{ }$

This problem is about Polynomial.

$(x + 7)^2 = (x + 7)(x + 7)$

$(x + 7)^2 = x^2 + 7x + 7x + 7(7)$

$(x + 7)^2 = x^2 + 14x + 49$

$x^2 + 14x + 49$ is a polynomial.

$x + 7$ is polynomial.

It demonstrates the closure property of multiplication.
