The perimeter of the figure is 58 units

The area of the figure is 130 unit square

Your question is not properly formatted and the diagram required to solve the question is missing.

I've included the appropriate diagram.

To calculate the perimeter of the shape, we simply add up the side lengths of the visible parts of the figure.

Having said that, the perimeter is:

Perimeter = 7 + 8 + 5 + 8 + 3 + 6 + 3 + 5 + 7 + 6

Perimeter = 58

To calculate the area, we use a different approach.

First, we split the figure into 3, we then calculate the area of each sub-figure, and then we add up the calculated areas.

From left to right, we have:

Rectangle 1

Length = 7\\Width = 6

Rectangle 2

Length = 5\\Width = 6+8 = 14

Rectangle 3

Length = 3\\Width = 6

The area of a rectangle is:

Area = Length * Width

So, the area of the figure is:

Area = 7 * 6 + 5 * 14 + 3 * 6

Area = 130

What is the slope-intercept equation of the line below? ​
emmasim [6.3K]

Answer:

y = -x-2

Step-by-step explanation:

We are given a slope of -1 and the y intercept of -2

The slope intercept form of the equation for a line is

y = mx+b

where m is the slope and b is the y intercept

y = -1x +-2

y = -x-2

Choose the equation that represents the line that passes through the point (6,-3,) and has a slope of 1/2
dezoksy [38]

Answer:

y=\frac{1}{2}x-6

Step-by-step explanation:

The general equation of a line: y = ax+b

In our case <em>a</em> is given

a=\frac{1}{2}

Now we plug in for <em>a</em> and we get:

y=\frac{1}{2}*x+b

Now we plug in our coordinates into this equation and we solve for <em>b</em>

-3=\frac{1}{2}*6+b\\b = -6

So the equation of the line is y=\frac{1}{2}x-6
