Answer:
4x^2-2x+7
Step-by-step explanation:
To find 50% or half, of 31, you can just add 31 + 31.
Or, 31 x 2.
Or even the longer way, we know 3 + 3 = 6. So we can just add 0's: 30 + 30 = 60. That leaves us with the 1's. 1 + 1 = 2.
Take our 60 from earlier, and add 2. 60 + 2 = 62.
Check your answer. 62/2 = 31.
Your answer is 62
