Step-by-step explanation:
You would multiply 4 and 3, and 2 and 9 separately, then add them, then subtract 40. Remember PEMDAS.
(4*3) + (2*9) - 40
12 + 18 - 40
-10
Hope that helps

Answer: y = 78</h3>
==================================
Justification #1: Angle x is 78 degrees as these two angles are corresponding angles (congruent due to the parallel lines). We also know that y = x because they are vertical angles. So by the transitive property, y = 78
Justification #2: The parallel lines mean that the alternate exterior angles are congruent, so y = 78 through one step (instead of multiple steps in the prior justification)
4=3
5=4
6=2
7=5
8=6
9=4
10= 16
16=31
18=36
