7. find de ( triangle mid-segment theorems)

45 units

Step-by-step explanation:

See the given diagram with the question here.

The point D and point E are the midpoints of line segments AC and BC respectively.

Therefore, the length of the line joining points D and E will be half of length AB.

Now, given that AB = 11x - 25 and DE = 4x + 1.

Hence, ( 11x - 25 ) = 2 ( 4x + 1 )

⇒ 3x = 33

⇒ x = 11

Therefore, length DE = 4x + 1 = 4 ( 11 ) + 1 = 45 units. (Answer)

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it
