Lola rode her bike for 7/10 of an hour on Saturday, and 3/5 of an hour on Sunday.
Fed [463]

Answer:

She rode 1/10 of an hour more on Saturday

Step-by-step explanation:

Take the time she rode on Sunday and subtract that from Saturday

7/10 - 3/5

Get a common denominator

7/10 - 3/5*2/2

7/10 - 6/10

1/10

Consider the following polynomial.
vfiekz [6]

Answer:

The equivalent factored form of this equation is (x² + 49)(x - 6)

Step-by-step explanation:

<em>x³ - 6x² + 49x - 294</em>

First, group the first and second terms together and group the last two terms together.

<em>(x³ - 6x²) + (49x - 294)</em>

Find the greatest common factor of both parentheses and factor them.  

x²(x - 6) + 49(x - 6)

Now, since the two terms in the parentheses are the same, then we have factored the equation correctly.

So, the factored form of the equation is (x² + 49)(x - 6)
