Answer:(6,-2)

Step-by-step explanation:

M is the midpoint of AB then ,

M = \frac{A+B}{2}

5=\frac{x+4}{2}     ,     -2=\frac{y-2}{2}

10=x+4  ,      -4=y-2

x=6          ,      y= -2

so, B= (6,-2)

If x-9 is a factor of x-5x-36 what is the other factor
dimaraw [331]
The other factor would be (x + 4). We can find this by using synthetic division. To do this, we must first find the divisor, which would be 9, if we let x - 9 equal to zero and solve for x. Then, for the dividend, we can use the coefficients and constant term values. 
<u>9</u>| 1  -5  -36
<u>         9  36</u>
     1  4  0
Therefore, the other expression (x + 9) would be (x + 4). Hope this helped!

The extensions of the legs AB and CD of a trapezoid ABCD intersect at point E. Find the lengths of the sides of △AED if AB=5cm,
Lynna [10]

Answer:

  AE = 15 cm; ED = 18 cm; AD = 15 cm (given)

Step-by-step explanation:

ΔBEC ~ ΔAED so ...

   AD/BC = AE/BE = (BE+AB)/BE = 1 + AB/BE

Substituting given numbers (lengths in centimeters), we have ...

  15/10 = 1 + 5/BE

  1/2 = 5/BE

  BE = 10

Similarly, ...

  1/2 = 6/CE

  CE = 12

Then the unknown sides are ...

  AE = AB + BE = 5 + 10 = 15 . . . cm

  ED = CE + CD = 12 + 6 = 18 . . . cm
