Answer:
28
Step-by-step explanation:
So let's start by subtracting 9 from 121.
We get 112, and all we have to do now is divide it by 4.
our answer is 28.
Dang, Ming's pretty popular.
That's Intersecting Secants, and we get
EC × ED = EB × EA
(x+4)(x+4+1) = (x+1)(x+1+11)
(x+4)(x+5) = (x+1)(x+12)
x^2 + 9x + 20 = x^2 + 13x + 12
8 = 4 x
x = 2
Check: 3(14)=42 6(7)=42 good
