Simplify the polynomials by combining like terms 3x 5x 4x

Hello! Combining like terms is just a fancy way of saying add all these numbers together. As long as numbers have the same variable (in this case x) and the same exponent (they don't have any in this case), you can add them together like normal. So! 3x + 5x +4x is the same as 3+5+4. Your simplified polynomial is 12x. Good luck with the math homework!

5 gallons x gallons

------------- = ----------------

12 hours 240 hours

using cross products

5 * 240 = 12 * x

1200 = 12 x

divide each side by 12

1200/12 = 12x/12

100 =x

You will need 100 gallons

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.
