Answer:

64/7 years

9.143 years

Step-by-step explanation:

$Simple Interest = \\ \frac{Principal \times Rate \times Time}{100}$

$Time = \frac{simple \: interest \times 100}{Principal \times Rate}$

$Principal = 400 \\ Rate = 14 \\ Time = \\ simple \: interest = 512$

Input the values

$Time = \frac{512 \times 100}{400 \times 14} \\ Time = \frac{51200}{5600} \\$

$Time = \frac{64}{7} \\ Time = 9.142 \: years \\ best \: answer \: = \frac{64}{7} years$

olganol [36]

Answer:

The answer to your question is letter A

Step-by-step explanation:

Polynomial 4x¹⁰ + 9x¹⁰

To sum or subtract polynomials, just look for like terms and do the operations considering the rules of signs.

In this problem both terms are like terms, then we add the coefficients and write the variable without a change.

4x¹⁰ + 9x¹⁰ = 13x¹⁰
