Answer:
The two lines of reflection are 
and 
Step-by-step explanation:
I will attach a file with the graph of the rectangle and the lines of reflection.
We know that RSTU is a rectangle with vertices at 
, 
,
and 
The first step is to draw the vertices on the plane and them the rectangle.
The rectangle is a symmetrical figure. Therefore if we want to carry the rectangle onto itself using a line of reflection this line must goes through the centroid of the rectangle.
Given that we have a rectangle whose width is 
and its length is 
its centroid will be place at 
.
Looking at the graph and using this information we find that the two lines of reflection are and .
When you are seeing which number is bigger first you look at the first digit
<u></u>0.<u>8</u>3 or 0.<u>8</u>02
^8 ^8
If they equal the same, look at the second digit
0.8<u>3</u> or 0.8<u>0</u>2
^3 ^0
3 is greater than 0
<u>0.83 is larger
</u>
you can also look at it this way:
0.83 = 0.830
What is bigger
0.802 or 0.830?
0.83 is bigger
Total surface area of the cylinder= 2*area of base+lateral area=
=2*1962.5 + <span>194.2 = 4119.2 cm²
1m=100 cm
1m² = (100 cm)²
1m²=10000cm²
</span>4119.2 cm² *(1m²/10000 cm²)= 0.41192 m²

Answer:
a +9b +c
Step-by-step explanation:
(14a+3b-6c) -(7a-2b-10c) -(6a-4b+3c)
= a(14 -7 -6) +b(3 +2 +4) +c(-6 +10 -3)
= a +9b +c
