Answer:

clockwise from left, the missing side lengths are 8 m, 13 m, 8 m

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of its sides. Sides with the same hash mark have the same length, so the perimeter (in meters) is ...

38 = (3x+1) +(2x) +(9) +(2x)

38 = 7x +10

28 = 7x . . . . . . subtract 10

4 = x . . . . . . . . divide by 7

Then the short sides are ...

2x = 2·4 = 8 . . . meters

and the long side is ...

3x+1 = 3·4 +1 = 13 . . . meters

What is the slope-intercept equation of the line going through (3, -6) and

jok3333 [9.3K]

Hi there!

$\large\boxed{D. \text{ }y = -4x + 6}$

To derive an equation given the points, we can use the slope formula:

$slope = \frac{y_{2}-y_{1}}{x_{2}-x{1}}$

Plug in the corresponding coordinates:

$slope = \frac{-6-2}{3-1}$

Simplify:

$slope = \frac{-8}{2} = -4$

Therefore, we have:

y = -4x + b

Plug in the x and y values for a coordinate to solve for b:

2 = -4(1) + b

2 = -4 + b

b = 6

The equation is:

y = -4x + 6. The correct answer is D.

What is the width of a rectangle with length 5.5 cm and area 220 cm^2

Reika [66]

In the given question it is given that the length of the rectangle is 5.5 cm and the area of the rectangle is 220 cm^2.
Length of the rectangle = 5.5 cm
Area of the rectangle = 220 cm^2
Then we already know that
Area of a rectangle = Length * width
So Width of the rectangle = Area of the rectangle/ Length
   = 220/5.5
   = 2200/55
   = 40
So the width of the rectangle is 40 cm.<span>Hope that you have got the answer you were looking for.
