Answer:

Step-by-step explanation:

In the 3rd question, we are given the equation x ^ 3 + x ^ 2 + 2x + 24. One of the factors is x + 3. Now, we can use long division to find that the equation we have left is x^2 - 2x - 8. We can just factor this to get (x - 4) (x + 2). In the 3rd question, possible factors for the coefficient are 1, 2, -1, -2. Possible factors for the constant are 1, 7, -1, -7. Now, we can try out all of them. The possible factors are 1, 7, -1, -7, 2, 14, -2, -14.

Write the ratio as a fraction in simplest form.<br><br> 10.8 seconds : 36 feet <br><br> (Show work)

vodka [1.7K]

Answer: Ratio as a fraction in simplest form is :

$\frac{27}{1}=27$

Step-by-step explanation:

Since we have given that

10.8 seconds : 36 feet

As we know that

$1\ second=\frac{1}{60}\ mile\\\\1\ second=90\ feet$

So, we use it :

10.8 seconds : 36 feet

$=10.8\times 90\ feet:36\ feet\\\\=972:36\\\\=27:1$

Hence, Ratio as a fraction in simplest form is :

$\frac{27}{1}=27$
