Step-by-step explanation:
By the secant-secant theorem, (AC)(BC)=(DC)(x+DC)
Substituting in the given values, (21)(9)=(8)(8+x)
So, 189=64+8x, meaning x = 15.625, or about 15.63.
2 left for Cameron the reason why is because in total there is 17
1 friend =3 pancakes
3•5=15 pancakes eaten
17-15=2
Step-by-step explanation:
21-11=10
10:2=5
X= rad 13^2-5^2= 169-25=144=12
X=12

Hope this helps :)
Answer:
x1 = 0
x2 = 3
Step-by-step explanation:
If that's the right equation we can now just simplify it a bit.
Cause now it becomes obvious that we can break out x and make it into a parenthesis:
And now there's two possibilities for what x could be. Either, x is 0:
Or, the parenthesis is 0, which means that x is 3 (because 3-3=0) :
So x has two answers:
x1 = 0
x2 = 3
