  2. When 4 is added to 3x , algebrically it is written as "3x + 4".
  3. When (3x + 4) is squared completely , algebrically it is written as - {(3x + 4)}^{2}  = 9 {x}^{2}  + 24x + 16

PLEASE ANSWER + BRAINLIEST!!!!
Verizon [17]

Answer: 2526 dollars

=============================

Work Shown:

Plug n = 400,000 into the function and simplify

f(n) = 939 + 5.29*(n-100,000)/(1,000)

f(400,000) = 939 + 5.29*(400,000-100,000)/(1,000)

f(400,000) = 939 + 5.29*(300,000)/(1,000)

f(400,000) = 939 + 5.29*(300)

f(400,000) = 939 + 1,587

f(400,000) = 2526
