(2-a)^2 + 3(2-a)
A^2 -2a + 4 + 6 -3a
A^2 -5a +10
2/10 because there are 10 cards and there are 5 circles and 3 triangles
Answer:
Let's assume the number be 100.
According to the problem , 100 is increased by 100%.
So, new number will be 100+100=200
Now 200 will decreased by 20%.
So, 20% of 200= 0.20*200= 40.
So, again the number has been changed into 200+40=240.
So, x=240
