Sorry, I misinterpreted the question before.\\\\
4^20+4^20+4^20+4^20 \\\\
4(4^20)\\\\
4^21\\\\
900=(1/2)*b*10*15
1800=150b
b=12
I hope you can figure out FC with this info.
Answer:
x = - 3 with multiplicity 2
Step-by-step explanation:
f(x) = (x - 3)(x + 3)(x + 3) = (x - 3)(x + 3)²
Equating each factor to zero and solving for x
x - 3 = 0 ⇒ x = 3 with multiplicity 1
x + 3 = 0 ⇒ x = - 3
x + 3 = 0 ⇒ x = -3
Thus x = - 3 has multiplicity of 2
The fact that the factor is squared gives the multiplicity
(x + 3)³ has root - 3 of multiplicity 3
