You are correct on question 1, it is C.
For the second one you could try plugging in the numbers to make them = each other on both sides. I'll use the right answer just to show how to do this type of problem. D is the correct answer. 

2*0.29^2-3*0.29+4=0.29+3

Solve these with pemdas.

Solve for the right side first: 0.29+3=3.29

Then: 0.29^2=0.0841 let's plug the numbers in after every time we solve something.

2*0.0841-3*0.29+4=3.29

2*0.0841=0.1682

We have: 0.1682-3*0.29+4=3.29

Multiply 3*0.29=0.87

0.1682-0.87+4=3.29

Now we subtract 0.87 from 0.1682 and then add 4= 3.2982 (round) and your answer is..

3.29=3.29

Try it with 1.71!
