ABCD is a trapezoid with median EF. a. AB = 15, DC = 11, then EF = ? b. EF = 14, DC = 10, then AB = ? c. EF = 18, AB = (5n - 9),
Reptile [31]
The median of the trapezoid is the average of the bases. If we draw the trapezoid that is being described in this item, we will deduce that AB and DC are the bases and EF is given to be the median.

 For this item,
                        EF = (AB + CD) / 2

Part A:
                      EF = (15 + 11) / 2 = 13

Part B:
                      AB = 2EF - CD
                      AB = (2)(14) - 10 = 18

Part C:
                       18 = ((5n - 9) + (2n + 3))/2
                        18 = (7n - 6) / 2
                                 n = 6

Part D:
                  2y + 4 = ((5y + 2) + (-3y + 8))/2

                     y = 1

EF = 2(1) + 4 = 6
AB = (5(1) + 2 = 7
AB = -3(1) + 8 = 5

Solve the equation using the method of factorisation-
saul85 [17]

Answer:

X = 9,X= -5, a =  2, b = -13

Step-by-step explanation:

For (1),

Using Cross-factorization,

it can be reduced to (X - 9)(X + 5) = 0

Equate each factor to 0:

we have X = 9 and X = -5

For (2),

It is the case of completing the Square,

add 4 so we get the completed square ( we want the form X^2 + 2a + a^2)

(X^2 + 4X + 4) - 9

can be simplified to (X+2)^2 -9

However since we added 4 it means we have to subtract 4

So it becomes (X+2)^2 -9 -4

= (X+2)^2 -13
