Answer:
Step-by-step explanation:
First, you can reduce it
4(n^2-11n+30)
This should make it easier to work with. But remember, keep the 4 there. You cannot just get rid of it because it would change the value of the equation
Now find factors of 30 that have a difference or ad up to 11.
Factors of 30:
1, 30
2, 15
3, 10
5, 6
Ahh yes, 5 and 6 add to 11
4(n-5)(n-6)
I'm guessing the question is "how far does he have to walk to the store from where he is"
if he is walking home, then hmm
distance from store to school=1.8/2 since it is halfway, so 0.9 miles
he has walked 0.36 miles
so he needs to walk 0.90-0.36=0.54 miles
he needs to talk 0.54 miles to get to the store
Answer:
1) 0.5
2)-2
3)-23
Step-by-step explanation:
1) -3×1=-3
-3+2.5= 0.5
2) -3×1.5=-4.5
-4.5+2.5= -2
3) -3×8.5=-25.5
-25.5+2.5=-23
Answer:
18.6
Step-by-step explanation:
Adding -20.4 to 39 is the same as subtracting 20.4 from 39. 39 - 20.4 = 18.6.
