Search it up on safari and you’ll find the answer
BD = BA + AD
51 = 26 + AD
-26 on both sides
AD = 25
Yes it should, 0 is still a number even though it’s value is nothing. You can’t get to -1 without 0.

Step-by-step explanation:
Answer:
AE = 4
Step-by-step explanation:
Use the formula
AE*EC = DE*EB
Since we don't know AE or EC, let AE = x and then EC will = 16 - x. The formula then becomes
x(16 - x) = 8(6)

Getting everything on one side and setting it equal to 0 will allow us to factor for x:

Factoring that gives you that
x = 4 and x = 12. That means that one of those sements has a length of 4 and the other has a length of 12. AE is shorter so it's 4 and EC = 12
