y = x³ + 3x² - x - 3
0 = x³ + 3x² - x - 3
0 = x²(x) + x²(3) - 1(x) - 1(3)
0 = x²(x + 3) - 1(x + 3)
0 = (x² - 1)(x + 3)
0 = (x² + x - x - 1)(x + 3)
0 = (x(x) + x(1) - 1(x) - 1(1))(x + 3)
0 = (x(x + 1) - 1(x + 1))(x + 3)
0 = (x - 1)(x + 1)(x + 3)
0 = x - 1 or 0 = x + 1 or 0 = x + 3
+ 1 + 1 - 1 - 1 - 3 - 3
1 = x or -1 = x or -3 = x

zachary has coins of the coins 3/6 are nickles, 2/6 dimes, rest are quarters. What is the ratio of zacharies nickles, to dimes t

lesya692 [45]

Answer:

The ratio of zacharies nickels to dimes to quarters is <u>3 : 2 : 1</u>.

Step-by-step explanation:

Given:

Zachary has coins of the coins 3/6 are nickels, 2/6 dimes, rest are quarters.

Now, to get the ratio of zacharies nickels, to dimes to quarters.

So, as given dimes and nickels we find the quarters to get the ratio:

$\frac{3}{6} -\frac{2}{6}=\frac{3-2}{6} =\frac{1}{6}$ .

Thus, the quarters are 1/6.

Now, getting the ratio of the coins:

Nickels = 3/6 × 6 = 3

Dimes = 2/6 × 6 = 2

Quarters = 1/6 × 6 = 1

<em>Nickels : Dimes : Quarters = 3 : 2 : 1.</em>

Therefore, the ratio of zacharies nickels to dimes to quarters is 3 : 2 : 1.
