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:
20 kg
Step-by-step explanation:
12/3 = 4
4 x 2 = 8
12 + 8 = 20
Answer:
9r
Step-by-step explanation:
1.5r - 3r + 10.5r
10.5r + 1.5r = 12r
12r - 3r = 9r
Final Answer = 9r
Hello there friendo.
I believe the correct answer to your question would be (2*6) - (36/12).
I hope this can help you! :)
