Answer:
B) The perimeter of ABCD is 4 times the perimeter of A'B'C'D'.
D) The corresponding angles of ABCD and A'B'C'D' are congruent.
Step-by-step explanation:
If triangle BCD is rotated 180° clockwise and then dilated by a factor of 4 centered at the origin;
The area of ABCD is 16 (NOT 4 ) times the area of A'B'C'D'.
B) The perimeter of ABCD is 4 times the perimeter of AB'C'D'.
The corresponding sides of ABCD and A'B'C'D' are in the same proportion and are NOT congruent because dilation is not a rigid transformation.
D) The corresponding angles of ABCD and A'B'C'D' are congruent because the two shapes are similar.
It’s blank 1 kaiqkqpsnqk sorry I had to ask wet something
Step-by-step explanation:
put equation 1 in equation 2
If 1-x/x+1 is undefined then the bottom number must be 0
set
x+1=0
x=-1
Answer:
C
Step-by-step explanation:
Area is W×L. The area of the rectangle is 6x^(2) + 7x - 3.
So we write that as 6x^(2) + 7x - 3 = W×L
We can factor 6x^(2) + 7x - 3 to see the width and length.
Then, you get (2x + 3) (3x - 1) = W × L
Now you have to values for width and length
The formula for perimeter is 2W + 2L, you can choose which is width and which is length
Next, substitute the values in the formula: 2(2x + 3) + 2(3x - 1) and solve it. Done! :)
