-8m + 6 - 2m = 9(3m + 4) +5m
-10m + 6 = 9(3m + 4) + 5m
-10m + 6 = 27m + 36 + 5m
-10m + 6 = 32m + 36
6 = 42m + 36
-30 = 42m
-5/7 = m
m = -5/7
hope that helps, God bless!
Hi there!

Use the kinematic equation to solve for acceleration:

Where:
vf = final velocity
vi = initial velocity
t = time
Plug in the given values:

Answer:
x=12
Step-by-step explanation:
What we have here is a secant and tangent. Using this theorem,
Given the segments of a secant segment and a tangent segment which share an endpoint outside of a circle,
The product lengths of the secant segment and external secant segment equals the length of the tangent segment squared.
In other words,




The answer to your question is A
