Can someone help me with this problem ​
Alex_Xolod [135]

Answer:

<h2>A = 20</h2><h2>P = 6√10</h2>

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

A(-3, 0) , B(3, 2)

AB=\sqrt{(3-(-3))^2+(2-0)^2}=\sqrt{6^2+2^2}=\sqrt{36+4}=\sqrt{40}=\sqrt{4\cdot10}=\sqrt4\cdot\sqrt{10}=2\sqrt{10}

A(-3, 0), D(-2, -3)

AD=\sqrt{(-2-(-3))^2+(-3-0)^2}=\sqrt{1^2+(-3)^2}=\sqrt{1+9}=\sqrt{10}

AB = CD and AD = BC

The area of a rectangle:

A=(AB)(AD)

Substitute:

A=(2\sqrt{10})(\sqrt{10})=(2)(10)=20

The perimeter of a rectangle:

P=2(AB+AD)

Substitute:

P=2(2\sqrt{10}+\sqrt{10})=2(3\sqrt{10})=6\sqrt{10}

Thisssss oneeeeee :)?????
SCORPION-xisa [38]

Answer:

y = 3x - 5

Step-by-step explanation:

I used my calculator so that it would be faster.

But if you want work you have to find the slope then plug in.

To find the slope use points (1, -2) and (2, 1) use this formula \frac{y2 - y1}{x2 - x1}

Plug the points in \frac{1 - -2}{2-1} =\frac{3}{1} = 3

So your slope is 3

NOw Plug In (1, -2)

-2 = 3(1) + b (b represents the y- intercept)

-2 = 3 + b (subtract 3 on both sides)

-5 = b

The final equation is y = 3x - 5

Hope this helps ya!!
