D 20 units
I know this because 7+7=14 and 3+3=6. Then 6+14=20.
Answer:

Step-by-step explanation:
An infinite non-abelian group that has exactly six elements of finite order is,

Multiplication by concatenation can be done, for example,
, since
.
This group is non-commutative, because
is not equal to
(as this is not a relation in the given presentation).
Now, this is infinite, because we can have 'words' of
of any length (the only simplifications we can use is when
show up).
Therefore, any word (not containing
) containing more than one of
must have infinite order.
Answer:
I think it's 31cm^2
Step-by-step explanation:
I don't know the units. sorry if this doesn't help but i hope this does.
180 m
Step-by-step explanation:
Information given:
- length of Mrs. Flores' garden= 20 m
- width of Mrs. Flores' garden = 15 m
- Scale factor = 3
Since scale factor is 3, to get measurements of sides Mr. Sosa's garden, sides of Mrs. Flores's have to be multiplied by 3. Hence,
- length of Mr. Sosa's garden= 3×20= 60 m
- width of Mr. Sosa's garden= 3×15= 45 m
Diagonal of a rectangle = √length²+width²
Let Diagonal = D,
D= √60²+45²
=√3600+2025
=√5625
=75 m
If Mr. Sosa cut his garden diagonally,
perimeter= length+width+diagonal
=60+45+75=180 m
