From the chord theorem we have:

1/2 or 50%
cuz there’s only two probable outcomes
First we rewrite the expression:
(4x ^ 3) * (2x) ^ - 4
Using properties of exponents we have:
(4x ^ 3) / (2x) ^ 4
Rewriting:
(4x ^ 3) / 16x ^ 4
(x ^ 3) / 4x ^ 4
(1) / (4x)
answer:
An equivalent expression is:
(1) / (4x)
option 1
Total amount of money = amount Jenny receives + amount Bailey receives
$30 = 2j + j
30 = 3j
