Answer:
The question is asking for the perimeter. There are three ways to answer this depending on the assumptions though so I'll let you choose.
Assumptions are basically the different scenarios
1st scenario being the trim covers the carpet and the tile, they'd need 48m of trim (12+12+4+8+8+4)
2nd scenario in which the trim covers the carpet but not the tiled area, they'd need 44m of trim (12+12+4+8)
3rd scenario where the trim only covers the the tiled area, 4m of trim
(just 4 since the tile only touches 4m of the wall)
Hope this helps!
Step-by-step explanation:
trim is just the perimeter since it covers the base of the wall
Answer:
is equivalent to
and 
is equivalent to
and
.
The expressions which are equivalent to neither:
and 
Step-by-step explanation:
Given the expressions:
1) 
2) 
To find:
The expressions equivalent to the given expressions.
or the expressions which are not equivalent to any of the given expressions.
Solution:
First of all, let us solve the brackets from the given expressions.
can be written as
(because when we multiply a negative sign with negative, it becomes positive.)
Similarly
can be written as
(because when we multiply a positive sign with negative, it becomes negative.)
Therefore, the answer is:
is equivalent to
and 
is equivalent to
and
.
The expressions which are equivalent to neither:
and 
RSU+UST=RST
78+3x-12=6x+12
3x+66=6x+12
3x=54
x=18
108+12=120
∠RST=120°
The answer is Not Proportional. I have this test too. Hope it helps!
