First, let's start off by simplifying as much as possible before factoring.
5d^2 - 50d + 125
We can divide all the numbers by 5 in order to simplify it:
5(d^2 - 10d + 25)
Now all we need to do is factor.
Since -5*-5 = 25 and -5 - 5 = -10, we can use this to factor:
5(d - 5)(d - 5)
Or
5(d - 5)^2
She spent 5.4 on tip so her overall total is $41.40
Answer:
A and C
Step-by-step explanation:
Nothing much, just add 2 1/2 to 3 2/3 and subtract 2 1/2 from 3 2/3
0.20km is the answer.
