Sam opened a money-market account that pays 2% simple interest. He started the account with $7,000 and made no further deposits.

Juliette [100K]

Answer: $7,420.00 = 3 years
(I = A - P = $420.00)

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year.

Solving our equation:
A = 7000(1 + (0.02 × 3)) = 7420
A = $7,420.00

The total amount accrued, principal plus interest, from simple interest on a principal of $7,000.00 at a rate of 2% per year for 3 years is $7,420.00.

(K² – 30k - 18 - 4K²) ÷ (3+k).

Alexxandr [17]

Answer:

$k^2-30k-18-4k^2=(k+3)(-3k-21)+45$

Step-by-step explanation:

Given:

$(k^2-30k-18-4k^2):(3+k)$

Consider the expression $k^2-30k-18-4k^2$ . First, add the like term $k^2$ and $-4k^2:$

$k^2-4k^2=-3k^2$

Now, this expression is

$-3k^2-30k-18$

Divide $-3k^2-30k-18$ by $k+3.$ Multiply $k+3$ by $-3k$ and subtract the result from the $-3k^2-30k-18$ to eliminate the highest term $-3k^2:$

$-3k^2-30k-18-(-3k)(k+3)=-3k^2-30k-18+3k^2+9k=-21k-18$

Multiply $k+3$ by -21 and subtract the result from $-21k-18:$

$-21k-18-(-21)(k+3)=-21k-18+21k+63=45$

Hence,

$k^2-30k-18-4k^2=(k+3)(-3k-21)+45$
