Answer:

<h2>c).</h2>

5x² - 50x + 120

Factor out the LCF which is 5

We have

5( x² - 10x + 24)

Write 10x as a difference

That's

5( x² - 6x - 4x + 24)

Simplify

Factor the expression

5 [ x ( x - 6) - 4( x - 6) ]

Factor out x - 4 from the expression

We have the final answer as

<h2>5 ( x - 4)( x - 6)</h2>

<h2>f).</h2>

2x² - 6x - 260

Factor out 2 from the expression

That's

2 ( x² - 3x - 130)

Write 3x as a difference

That's

2 ( x² + 10x - 13x - 130)

Factorize the expression

2 [ x ( x + 10) - 13 ( x + 10) ]

Factor out x + 10 from the expression

We have the final answer as

<h2>2( x + 10)( x - 13)</h2>

Hope this helps you

Answer:

The gallons of gas the tank contain now is <u>35 1/12</u>.

Step-by-step explanation:

Given:

Fuel tank contains 1 3/4 gallons of gasoline.

Casey adds 33 1/3 gallons of  gasoline to the tank.

Now, to find the total gallons of gas the tank contain.

Converting the mixed fractions into improper.

Gallons of gasoline in fuel tank =1\frac{3}{4}=\frac{7}{4}.

Gallons of gasoline Casey adds =33\frac{1}{3} =\frac{100}{3}.

<u>According to question:</u>

By adding we get the total gallons of gasoline now tank contain:

\frac{7}{4} +\frac{100}{3}

=\frac{7\times 3+100\times 4}{12}

=\frac{21+400}{12}

=\frac{421}{12}

=35\frac{1}{12}

Therefore, the gallons of gas the tank contain now is 35 1/12.
