Well, first, let's label the variables for our equation:
240 Miles per day
Traveled for 4 days
_________________________________________
Now, let's set up an equation to help us:
240x = ?
Since they're trying to figure out how many miles the family traveled after 4 days, and, they're going 240 miles each day, we should plug in a 4 where 'x' is:
240 ( 4 ) = ?
Now, we multiply:
240
× 4
________
800
+ 160
________
960
Answer: The family traveled 960 miles in 4 days.

(3n-2) x (4n+1) =0
All you need to do is to find what value of n makes each factor equal 0.
First Term:
3n-2 = 0
3n = 2
n = 2/3
Second Term:
4n+1 = 0
4n = -1
n = -1/4
n ={2/3, -1/4}
26 people. There will be no ice cream left. 19.5/.75=26 people
Answer:
(x - 9)(x - 9)
Step-by-step explanation:
<em>Hey there!</em>
Well to factor,
x^2-18x+81
we need to figure out what times what equal 81 and adds together to get -18.
-9*-9 = 81
-9 + -9 = -18
x*x = x^2
Factored - (x - 9)(x - 9)
<em>Hope this helps :)</em>
