PLZ HELP ME I WILL TRY GIVE BRAINIEST Pilar wanted to use estimation to solve a decimal addition problem. She correctly used estimation to rewrite the problem as 12 + 3 + 5 + 6. What could her original problem have been?
0 12.38 + 4.45 + 4.14 + 6.7
0 12.5 + 3.05 + 5.23 + 0.6
0 11.5011 + 3.6 + 5.17 + 5.7
0 11.75 + 3.299 + 5.31 + 6.27

11.75 + 3.299 + 5.31 + 6.27

Step-by-step explanation:

every decimal .5 and above gets rounded up, below .5 gets rounded down

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
