In trapezoid EFGH , EF¯¯¯¯¯ and HG¯¯¯¯¯¯ are the bases. Point J is the midpoint of EH¯¯¯¯¯¯ and point K is the midpoint of FG¯¯¯¯¯ . EF=3x+2 , HG=7x−2 , and JK=25 . What is the value of x?

Enter your answer in the box.

x =

9514 1404 393

  x = 5

Step-by-step explanation:

The sum of the base lengths is twice the length of the midline.

  EF +HG = 2JK

  (3x +2) +(7x -2) = 2(25)

  10x = 50 . . . . . . simplify

  x = 5 . . . . . . . . . divide by 10

the answer is x=5

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
