A disjunction is false if both parts of the disjunction are false; otherwise, it is true
----------------------------------------------
Choice A
4-3=2 is false
6*3=9 is false
both parts are false, so overall the entire disjunction is false
----------------------------------------------
Choice B
5*6=30 is true
3+4=7 is true
Neither part is false, so overall the entire thing is true
----------------------------------------------
Choice C
8+3=11 is true
5*4=23 is false
While second piece is false, the overall disjunction is true. The first part (true) makes the whole thing true.
----------------------------------------------
Choice D
7+6=13 is true
5*2=10 is true
Neither part is false, so overall the entire thing is true
----------------------------------------------
----------------------------------------------
In summary, we have
A. False
B. True
C. True
D. True
Making choice A the only answer that is false. So choice A is the final answer

Answer:
The answer is 53
Step-by-step explanation:
We know that all the angles in a triangle add up to 180. So we do 37+90= 127
180-127= 53
Hope I helped!
Step-by-step explanation:
#1 eq → x + y = -13
#2 eq → x - 2y = -8
Elimination for x
x + y = -13
x - 2y = -8
________ _
3y = -5
y = -5/3 → value of y
Find x :
x + y = -13
x - 5/3 = -13
x = -13 + 5/3
x = -39/3 + 5/3
x = -34/3 → value of x
