Answer:
43,200
Step-by-step explanation:
B) the one that has the sides 4 & 8 and 3 & 6.
The length on both of these rectangles are twice as long as the width
one rectangle goes from a width of 4 and its length is doubled to a length of 8
it is similar to the 3 & 6 because the width of 3 is doubled to get the length of 6
hope this helps
Let's start with a picture.
We see RST is smaller, and BC is parallel to but in the opposite direction to its corresponding segment ST. Both have slope -1.
If we look at the difference of points (technically called vectors but we don't have to go there) we get
C-B=(-2,2)
T-S=(1,-1)
Without further calculation we can see T-S is half the length of C-B.
The problem asks for a dilation followed by a reflection. We know the dilation scale is k=1/2 because the new triangle is half the size.
After dilation we get A'B'C':
A'(3,2), B'(-1,0), C'(-2,1)
We see now we need a reflection that flips the coordinates x and y. That's the +45° line through the origin, namely y=x.
Answer: k=1/2, y=x

Answer:
B.
Step-by-step explanation:
The negative of a negative is a positive, so B is your choice. Think of it anothe way, if it helps. Imagine that the expression is this:
(-2) + (-1)(-3) since every subtraction problem can be rewritten as an addition problem.
We would first, by orders of operation, multiply the -1 and the -3 getting 3. Then the problem would simplify down to -2 + 3
Just another idea to ponder...
