Answer:
mmm... i think its 6-
Step-by-step explanation:
Answer:
1.
( n + 4 ) - 9
- n - 4 - 9
- n - 13
2.
40 = x - 1
- x = - 1 + 40
- x = 39
Step-by-step explanation:
I duno if this is right...
Distance:time=25:13.7
ratio and propriton
4min=60sec*4=240sec
25/13.7=?/240
times both sides by 240*13.7
25*240=13.7?
6000=13.7?
divide both sides by 13.7
437.9562=?
about 438 meters
Answer:
Solution given:

now
f(x)+g(x)=
....(1)
now
factoring x²+6x-40
we get
x²+10x-4x-40
x(x+10)-4(x+10)
(x+10)(x-4)
now substituting in equation 1 ,we get
f(x)+g(x)=
taking l.c.m
=
=now
opening bracket

=
So
answer is :
B. 
Answer:
Symmetric property
Step-by-step explanation:
In this question, we are given a set of options to choose the correct answer from which gives the definition of the property in the question.
The correct answer here is the symmetric property. So why is this correct?
In proper terms, we refer to this property as the symmetric property of congruence.
It is a way of referring to the fact that when writing the way two congruent angles are equal to each other by the property of congruence, we can move in either of the two directions.
Either way we write, we are absolutely correct to indicate that both angles are equal due to the property of congruence.
