What is the combined perimeter of these two rectangles 4x+5 and 2x+7 and 3x+14 and 3x

Marysya12 [62]

Answer:

The combined perimeter is 24x + 52 units

Explanation:

1- Let's get the perimeter of the first rectangle:

The dimensions of the first rectangle are 4x+5 and 2x+7 units

Perimeter of rectangle = 2(length + width)

Perimeter of first rectangle = 2 (4x+5+2x+7)

Perimeter of first rectangle = 2 (6x + 12)

Perimeter of first rectangle = 12x + 24 units

2- Let's get the perimeter of the second rectangle:

The dimensions of the second rectangle are 3x+14 and 3x units

Perimeter of rectangle = 2(length + width)

Perimeter of second rectangle = 2 (3x+14+3x)

Perimeter of second rectangle = 2 (6x + 14)

Perimeter of second rectangle = 12x + 28 units

3- Finally, let's get the combined perimeter:

Combined perimeter will be the summation of the two perimeters

Combined perimeter = 12x + 24 + 12x + 28

Combined perimeter = 24x + 52 units

Hope this helps :)

Please provide the answer and an explanation why that is the answer.

Komok [63]

Slope formula = y=mx+b

2x+4y=12
Minus 2x from both sides

4y= -2x+12

Divide 4 from both sides
Y= -1/2x + 4

Hope this helps!

Write the standard form of the equation of the circle with center (7,1) that also contains the point (−1,−5).

Karo-lina-s [1.5K]

Answer:

$(x-7)^2+(y-1)^2=100$

Step-by-step explanation:

1) Find the radius

We can do this by using the distance equation with the centre (7,1) and the given point (-1,-5):

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ where the two points are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in the points (7,1) and (-1,-5)

$d=\sqrt{(-1-7)^2+(-5-1)^2}\\d=\sqrt{(-8)^2+(-6)^2}\\d=\sqrt{64+36}\\d=\sqrt{100}\\d=10$

Therefore, the radius of the circle is 10 units.

2) Plug the data into the equation of a circle

Equation of a circle (when not centred at the origin):

$(x-h)^2+(y-k)^2=r^2$ where the centre is $(h,k)$ and r is the radius

Plug in the centre (7,1) as (h,k)

$(x-7)^2+(y-1)^2=r^2$

Plug in the radius 10

$(x-7)^2+(y-1)^2=10^2\\(x-7)^2+(y-1)^2=100$

I hope this helps!
