Answer:
28
Step-by-step explanation:
So this means to replace the r you see in 4r^2-8 with 3.
Let's do that:
4(3)^2-8
Now to simplify this just use pemdas or a calculator:
4(9)-8 since 3^2 means 3*3=9
36-8
28
42,812 and 62,812! You just add and subtract 10,000 from 52,812 and you will get the answer! Hope this helps!
I’m pretty sure it’s 4 < r < 4.1
