Answer:
x = √K - 2xh - h²/a
Step-by-step explanation:
a(x+h)²=k
a * x² + 2xh + h² = k
a * x² = K - 2xh - h²
x² = K - 2xh - h²/a
x = √K - 2xh - h²/a
Step-by-step explanation:
Square root is equivalent to 1/2 power:

Square root of 9 is 3. Multiply the exponents by 1/2 to get:

673 times 3 is equals 2019
673•3=2019
(f o g)(x) = f(g(x)) so we plug in the equation for g(x) where the x-variable is in f(x).
5(x + 1)³
5[(x + 1)(x + 1)(x + 1)]
5[(x² + 2x + 1)(x + 1)]
5(x³ + 3x² + 3x + 1)
(f o g)(x) = 5x³ + 15x² + 15x + 5
