Assumption:
△RST is congruent to △TXY
The vertices therefore correspond as follows.
From △TXY to △RST:
T <--> R
X <--> S
Y <--> T
Hence:
TX <--> RS
TY <--> RT
XY <--> ST
Answer:
12
Step-by-step explanation:
Original length: 3
Scale factor: 4
3 x 4 = 12
Answer:
F(1,5)
Step-by-step explanation:
This is a vertical parabola.
The vertex is at (1,4).
The directrix is y=3.
The distance from the vertex to the directrix is p=1
The focus is (1,4+p), which is (1,4+1)
Therefore the focus is (1,5)
9+7=16
My main thinking is that if you draw nine circle and put seven in all of them after that count it all together and you will get your answer which is 16.
