Answer:

x = 8.7

Step-by-step explanation:

The triangles are congruent, which means that the sides are proportional to each other. Line DE and line BE are proportional to each other. This means that:

8 = 12

We can simplify this down to

2 = 3

Now that we have this proportion we can apply it to Lines AE and EC

2(13) = 3x

26 = 3x

8.67 = x

Therefore x is equal to 8.67 (or 8.7 rounded)

Check:

8/12 = 0.6667

8.6667/13 = 0.6667

Since both are the same, the answer is correct.

The length of a rectangle is 55 meters less than 44 times the width. if the perimeter is 150150 meters, find the length and the
MrRa [10]
They did not state exactly what the width or length is. So in this case, let's name the number of width to be x. And thus we can derive to the conclusion of,

Width : x
Length : x-44 (from the 1st sentence of question)
So, We all know that a rectangle has 2 Lengths and 2 widths. So we can derive the conclusion that,
2(x)+2(x-44)=150150
2x+2x-88=150150
4x-88= 150150
4x= 150150+88=150238
4x=150238
x= 150238÷4

What is the slope of the line through (-9,6) and (-3,9)?
lina2011 [118]

Answer:

1/2

Step-by-step explanation:

To find the slope of a line through 2 point we use the formula

m = (y2-y1)/ (x2-x1)

    = (9-6)/(-3--9)

    = 3 /(-3+9)

    = 3 /6

    = 1/2
