AE x BE = DE x CE
6x5 = 30
6 x DE = 30
DE = 30/6 =5
DC = DE +CE = 5+6 =11
Answer is C) 11
Sometimes I’m pretty sure
Answer:
Factoring the term
we get 
Step-by-step explanation:
We need to factor the term 
First we can see that
is common in both terms
So, taking
common:

We can write
as 

Now we can solve
using the formula: 
We can write:

So, factoring the term
we get
