Answer: 4/15
Step-by-step explanation:
<span>The graphs are identical and intersect at infinitely many points.

First let's get rid of the parenthesis:
12 - 4x + 3x = 4 + 10 + 2x
Now group the x's on the left and the numbers on the right
-4x + 3x - 2x = 4 + 10 - 12
...and simplify
-3x = 2
divide by -3 to isolate x
x = -2/3
80+20 is ten times 8+2, if you factor out 10 from 80+20 we get 10(8+2)
ES is half of EF since a chord is bisected by the radius. ES = 10
