Answer:

54y² +255y +300

Step-by-step explanation:

Such an expression is simplified by eliminating parentheses and combining like terms.

<h3>Eliminate parentheses</h3>

Taking the given expression at face value, we have ...

{2(3y+6)-3(-4-y)}2(3y+6)−3(−4−y)

= {6y +12 +12 +3y}(6y +12) +12 +3y

= (9y +24)(6y +12) +12 +3y

= (9y)(6y +12) +24(6y +12) +12 +3y

= 54y² +108y +144y +288 +12 +3y

<h3>Combine like terms</h3>

= 54y² +(108 +144 +3)y +(288 +12)

= 54y² +255y +300

Answer:

$70,201.38

Step-by-step explanation:

To determine the principal amount, we can use the formula:

$P=\dfrac{A}{(1+\frac{r}{n})^{nt}}$

A = $200,000

r = 7% or 0.07

t = 15 years

n = 12

Now let's substitute our values.

$P=\dfrac{200,000}{(1+\frac{0.07}{12})^{12(15)}}$

$P=\dfrac{200,000}{(1.00583333333)^{12(15)}}$

$P=70,201.38$

So the principal needed to get 200,000 in 15 years is $70,201.38.
