Answer:

2/1

Step-by-step explanation:

Follow the formula: (y2 - y1) / (x2 - x1). So 4-(-4) and 2-(-2). A negative and a negative equal a positive so 8/4. Then simplify. Which gives you 2/1. Hope this helps.

A rectangle has the following vertices. Find the area of the rectangle. (9, −1), (−1, 7), (−5, 2), (5, −6)

stiks02 [169]

Answer: 82 sq. units .

Step-by-step explanation:

Let A (9, −1), B (−1, 7), C(−5, 2), D(5, −6) are the vertices of rectangle.

Then we plot them on graph ( as provided in attachment)

Length = AB $=\sqrt{(9+1)^2+(-1-7)^2}$ units [By distance formula : $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ ]

$=\sqrt{(10)^2+(-8)^2}=\sqrt{100+64}=\sqrt{164}=2\sqrt{41}$ units

Width = BC = $\sqrt{(-1+5)^2+(7-2)^2}$ units

$=\sqrt{4^2+5^2}\\\\=\sqrt{16+25}\\\\=\sqrt{41}$

Area = length x width

= $2\sqrt{41}\times\sqrt{41}=2\times41= 82\text{ sq. units}$

Hence, the area of the rectangle is 82 sq. units .

What is the simplest form of the expression? 3sqrt(24a^10b^6)?

Anastasy [175]

Answer:

$\text{The simplest form is }6\sqrt6a^5b^3$

Step-by-step explanation:

Given the expression $3sqrt(24a^{10}b^6)$ .

we have to find the simplest form of the expression.

$3sqrt(24a^{10}b^6)$

= $3(24^{\frac{1}{2}}a^{\frac{10}{2}}b^{\frac{6}{2}})$

= $3(24^{\frac{1}{2}}a^5b^3)$

= $6\sqrt6a^5b^3$

which is the simplest form of the given expression.
