This is just an algebraic problem, the correct option is:
<em>"Myra should have multiplied 4.5 and 2.1 first."</em>

How to evaluate an expression?</h3>
Here we want to evaluate the expression:
-31.7 + 4.5*x
in x = 2.1
This just means that we need to replace x by 2.1 in the given equation.
Now, what Myra does is:
-31.7 + 4.5*2.1 = -27.2*2.1
So she took the sum between -31.7 and 4.5 first, this is her mistake, you only would do that if the expression was:
(-31.7 + 4.5)*2.1
But in our expression:
-31.7 + 4.5*2.1
The first thing you need to solve is the product in the second term, so we get:
-31.7 + 4.5*2.1 = -31.7 + 9.45 = -22.25

B is the answer to ur question
The best thing I can say is use a online scientific calculator.
You need to construct at least 2 angle bisectors to help locate the incircle's center (aka the "incenter"). The incircle is the largest circle possible that is inside the triangle, that doesn't overflow or spill outside of the triangle. An angle bisector cuts an angle in half.
