An=3*(4^(n-1)) is the explicit
the recursive is <span>t_n = 4 * t_(n-1)</span>
3 because there are it takes 4 of 1/4 to complete 4/4 and make it one
Answer:
option C = (x+2)(x+1)
Option D = 3x^2+2x
Step-by-step explanation:
option C
(x+2)(x+1)= x*x+x+2x+2
(x+2)(x+1)= x^2 +3x + 2
X^2 : squared term
Option D = 3x^2+2x
3x^2 : squared term
