Just do the normal formula but don’t multiply it by pi and then add the pi symbol after.
Step-by-step explanation:
f(x) = x² - 2x - 3
g(x) = 4x²
f(g(x)) = f(4x²)
f(4x²) = (4x²)² - 2(4x²) - 3
= 16x⁴ - 8x² - 3
2(x - 4) + 7(x + 4)
(2x - 2 • 4) + (7x + 7 • 4)
9x + 20
Answer and explanation:
m∠4 = 32°
m∠2 is a vertical angle to m∠4
