The first one is
left at 2(A + B)
The second one is
A^2 + 2AB + B^2 The expanded version is greater than A^2 + B^2 See below for why.
(A + B)^2 / [2(A + B) ] = (A + B)/2 which is what is left over when (A + B)^2 is divided by the first one.
(A + B)^2 / (A^2 - B^2) = (A + B) * (A + B) / [(A + B) (A - B)] = (A + B) / (A - B) which is less than (A + B)/2 for (A - B)>2
The third one is just A^2 + B^2 which is smaller than the second one by an amount equal to 2AB. Since A and B are both > 0, 2 AB must be > 0
A^2 - B^2
Answer:
40 miles per hour.
Step-by-step explanation:
Divide the total amount of miles by the number of miles, in this case, 200 by 5 to find out how fast it traveled in 1 hour.
200/5=40
Answer:
I don’t know
Step-by-step explanation:
900/5280 = 90/528 = 45/264 = 15/88
CHECK: 15/88 * 5280 = 900
The answer to your question is = 15/88
HOPE THIS HELPS !!!!
