Answer:
x = 9; This problem is also true because 5x + 45 is equal to 5x + 45
Step-by-step explanation:
First you would distribute 5 into x and 9
5x + 45 = 5x + 45
Then we would divide both 45 on both sides by 5
5x + 45 = 5x + 45
÷5 ÷5
---------------------------
x = 9

Answer:
B' (16, 14)
Step-by-step explanation:
<em>Whenever we have a dilation with a scale factor b, we get the new point as:</em>
<em>Let original point be (x,y), then the dilation would make it (bx, by).</em>
<em />
There is a diagonal that goes through AC and another through BD. The midpoint of both the diagonal is same. Midpoint formula is:

<u>Midpoint of AC:</u>

Now let vertex B have coordinates (x,y). <u>Midpoint of BD:</u>

<em>Equate this to the midpoint of AC:</em>
<em>(x+2)/2=5</em>
<em>x+2 = 10</em>
<em>x = 8</em>
<em />
<em>and</em>
(y+1)/2=4
y+1=8
y = 7
Thus, B(8,7)
<em>recalling dilation of scale factor 2 rule we said at the beginning, B' would be twice of each coordinate. Hence B' = (16,14)</em>
It would depend on how big the thermos is, but I would say D

Step-by-step explanation:
The distance between two points, and is given by:
The endpoints are: Q(-5, -1), R(3, 7)
Point S is (4,-2).
The distance of S to Q is:
The distance of S to R is:
