Answer:=x3−7x2+4x+30

Step-by-step explanation:

(x−5)(x2−2x−6)

=(x+−5)(x2+−2x+−6)

=(x)(x2)+(x)(−2x)+(x)(−6)+(−5)(x2)+(−5)(−2x)+(−5)(−6)

=x3−2x2−6x−5x2+10x+30

=x3−7x2+4x+30

Find the equation of a line that has a slope of 1/2 and passes through the origin.
omeli [17]

Step-by-step explanation:

The equation of a line with slope m and y-intercept b is y = m x + b.  

This line goes through the point ( 0 ,0 ), so the y-intercept is zero.

We are given the slope as − 2 / 3.

The equation of the line is y= – 2 / 3 x + 0 = – 2 / 3 x

y = – 2 / 3 x

this is the question pls help me 4 friends evenly divided up an n-slice pizza. One of the friends, Harris, ate 1 fewer slice tha
Pani-rosa [81]

Answer:

\frac{n}{4}-1

Step-by-step explanation:

If we have a pizza that has n slices and we want to split it between 4 friends, then each friend will get \frac{n}{4} slices.

Now, Harris is one of those friends so he receives  \frac{n}{4}  slices, but he eats one less than he receives. Therefore, we subtract one from this expression to get our final answer of \frac{n}{4}-1.

Hope this helped!

Marat540 [252]

           (150 miles/week) x (1 gallon / 25 miles) x (3 $/gallon)

       =                      18            $/week .
