Answer:
Step-by-step explanation:
A) When the first equation is multiplied by 5 and the second equation by –6 ,
the equations become,
35x + 60y=54
-30x - 60y=60
Hence we can eliminate y by adding the equation.
B) When the first equation is multiplied by -5 and the second equation by 6 ,
the equations become,
-35x - 60y=54
30x + 60y=60
Hence we can eliminate y by adding the equation.
C) When the first equation is multiplied by -5 and the second equation by 7,
the equations become,
-35x - 60y=54
35x - 70y=60
Hence we can eliminate x by adding the equation.
D) When the first equation is multiplied by 5 and the second equation by -7,
the equations become,
35x + 60y=54
-35x - 70y=60
Hence we can eliminate x by adding the equation.
E) When the first equation is multiplied by -5 and the second equation by 10,
the equations become,
-35x - 60y=54
50x - 100y=60
Hence we can not eliminate x by adding the equation.

Answer:
D) AB = AB
Step-by-step explanation:
The reflexive property states that a value is equal to itself: x = x.
The reflexive property of length states that a length is equal to itself:
AB = AB
A) and C) are wrong. They represent the reflexive property of angles.
B) is wrong. It represents the symmetric property of length.
P= 2(1 + h)
P= 2(8 + 13)
P= 2(21)
P=42
Your answer is 42
