Answer:
Hi,
Sorry about that!
esto no es falso como tu actitud
Step-by-step explanation:
1. Only one
2. One point
3. Three
4. -2
do not know after that!
Hey mate...☺️
1. (1) only one((A).
(2) one(C).
(3) one or three(C).
(4) 7(C).
(5) 8(B).
2. (1) d(P,Q)+d(Q,R)= d(P,R)
d(P,Q)= 3-(-5)
= 3+5
= 8
d(Q,R)= 6-(-5)
= 6+5
= 11
d(P,R) = 6-3
= 3
According to the problem given,
LHS= d(P,Q)+ d(Q,R)
= 8+11= 19
RHS= d(P,R)= 3
LHS≠RHS
Therefore, given statement is false.
(2) d(P,R)+ d(R,Q)= d(P,Q)
d(P,R)= 6-3
= 3
d(R,Q)= 6-(-5)
= 6+5
= 11
d(P,Q)= 3-(-5)
= 3+5
= 8
According to the problem given,
LHS= d(P,R)+ d(R,Q)
= 3+11
= 14
RHS= d(P,Q)= 8
LHS≠RHS
Therefore, given statement is false.
(3) d(R,P)+ d(P,Q)= d(R,Q)
d(R,P)= 6-3
= 3
d(P,Q)= 3-(-5)
= 3+5
= 8
d(R,Q)= 6-(-5)
= 6+5
= 11
According to the problem given,
LHS= d(R,P)+ d(P,Q)
= 3+8
= 11
RHS= d(R,Q)= 11
LHS= RHS
Therefore, given statement is True.
(4) d(P,Q)- d(P,R)= d(Q,R)
d(P,Q)= 3-(-5)
= 3+5
= 8
d(P,R)= 6-3
= 3
d(Q,R)= 6-(-5)
= 6+5
= 11
According to the problem given,
LHS= d(P,Q)- d(P,R)
= 8-3
= 5
RHS= d(Q,R)= 11
LHS≠RHS
Therefore, statement is false.
3. (1) 3,6= 6-3= 3 units.
(2) -9,-1= -1-(-9)
= -1+9= 8 units.
(3) -4,5= 5-(-4)
= 5+4= 9 units.
(4) 0,-2= 0-(-2)
= 0+2= 2 units.
(5) x+3, x-3= x+3-(x+3)
= x+3-x+3
= 6 units.
(6) -25,-47= -25-(-47)
= -25+47
= 22 units.
(7) 80,-85= 80-(-85)
= 80+85
= 165 units.
