Answer: B. 
Step-by-step explanation:
The formula to find the compound amount (compounded yearly):-
, where P is the principal amount invested, is the rate of interest and t is time period.
As per given , we have
P=$5500 , r=5% = 0.05 and A = $7,739.05.
Substitute all the values in the formula , we get
Hence, the equation describes Meredith's investment based on t, the number of years she kept the account open :
Let's translate the expression step by step:
"Five less than..." 
we will have to subtract five from something
"two times a number" 
.
So, we have
"Five less than two times a number" 
.
This "is sixty-nine", where "is" means "is equal to". So, the equation is
which is option B
.5x=10+.25x
.25x=10

Polynomial A : x^4 + 2 x³ - x² + 7 x + 11 has a Quartic degree.
Polynomial B : x² + 4 x is a Quadratic binomial.
Polynomial D : 5 x² - 2 x + 4 has a Quadratic degree.
Answer:
Polynomial D : 3 x^5 + 2 is a Quintic binomial
