Answer:
hey hey are u why and who
Step-by-step explanation:
.
Let the equal sides of the isosceles Δ ABC be x.
Given that the perimeter of Δ ABC = 50m.
Therefore, 2x + AC = 50 --- (1)
It is also given that the perimeter of Δ ABD = 40m.
Therefore, x + BD + AD = 40
BD is the median of the Δ ABC. Therefore, D is the midpoint of AC.
So AD = CD.
Or, AD =
AC
Therefore, ![x + BD + \frac{1}{2} AC = 40](https://tex.z-dn.net/?f=x%20%2B%20BD%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20AC%20%3D%2040)
Multiply both sides by 2.
2x + 2BD + AC = 80
From (1), 2x + AC = 50.
Therefore, 2BD + 50 = 80
2BD = 80 - 50
2BD = 30
BD = 15m.

Answer: The equation is 24 + x = 56
Step-by-step explanation: x would be 32, but the set up would be 24 + x = 56, since both of their cookies equal 56.
(Im also assuming you meant 24 and not 242424, same with 56.
