Answer:
Refer to the chart below for help:
SSS: When all three sides are equal to each other on both triangles, the triangle is congruent
AAS: If two angles and a non-included (you can think of it as outside) side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
ASA: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
SAS: If any two angles and the included side are the same in both triangles, then the triangles are congruent.
First, let's see what the answer is when we follow this equation using PEMDAS.
5 + 4 x 2 + 6 - 2 x 2 - 1
5 + 8 + 6 - 4 - 1
14
Now, let's trying grouping 5 + 4 together, and solving it again.
(5 + 4) x 2 + 6 - 2 x 2 - 1
9 x 2 + 6 - 2 x 2 - 1
18 + 6 - 4 - 1
24 - 5
19
So, the parentheses go around 5 + 4 to get your answer!
