Answer:
The rectangle has a width of 18 inches and a height length of 8 inches.
Step-by-step explanation:
The perimeter of a rectangle is described by the equation:

where <em>l</em> is width, <em>h</em> is height, and <em>p</em> is perimeter.
We're also told that the total perimeter is 52 inches.
We're also told that the length is six inches less than three times the width. We can express that as
.
We can plug that definition of w into the perimeter equation to find the length:

Now we can take that and the given perimeter, and substitute those into the perimeter equation to find the width:

So the width is 18

Answer:

Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- Two points (-2,11) and (5,6) .
And we need to find out the slope of the equation between the two points. The slope of the line passing through two points , is given by ,
- Here the two points are (-2,11) and (5,6) .So put on the respective values ,
<u>Hence</u><u> the</u><u> </u><u>slope</u><u> of</u><u> the</u><u> line</u><u> is</u><u> </u><u>-</u><u>5</u><u>/</u><u>7</u><u> </u><u>.</u>
Answer (x represents the first direction and the y represents the second direction):
- (x - 3) × (y + 5)
- New bedroom: 7 ft × 15 ft. Her new bedroom is 5 sq. ft larger than her old bedroom
I hope this helps!
A line adds up to equal 180 degrees. And adjacent angles also add to equal 180 since they share a side on a line. So add them together and make them equal 180
9x - 7 + 8.5x + 4 = 180
17.5x - 3 = 180
17.5x = 183
x = 10.5
