The value of g(x) = 2[f(x)]² - 1 is g(x) = 8x² + 8x + 1
<h3>How to find a function?</h3>f(x) = 2x+1
Find
g(x) = 2[f(x)]² - 1
Hence,
g(x) = 2[2x + 1]² - 1
g(x) = 2[4x² + 4x + 1] - 1
g(x) = 8x² + 8x + 2 - 1
g(x) = 8x² + 8x + 1

Answer:
P=143
Step-by-step explanation:
So, we know that P and Q are supplementary angles. In other words:
We also know that P is 5 less than 4 times Q. Thus:
Substitute the second equation into the first:
Find Q. Combine like terms:
Add 5 to both sides:
Divide both sides by 5:
So, Q is 37 degrees.
Q and P are supplementary, which means that P is 180-37 or 143 degrees.
And we're done!
