points d and e are midpoints of the sides of triangle abc. the perimeter of the triangle is 48 units. what is the value of t?
a 2

b 3

c 6

d 8

     If points E and D are midpoints of triangle ABC, then the perimeter of the triangle is:AB + BC + CA = 48, or:
3 t + 3 t + 4 t + 4 t + 7 t + 6 = 4821 t = 48 - 621 t = 42t = 42 : 21t = 2 A.  2.

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.

Your question is not clear but if you can explain yourself i would be glad to .  just trying to : ))
