Answer:
Answer: The correct option is (D) P″(9, -12) and Q″(15, -3).
Step-by-step explanation: Given that triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″.
The co-ordinates of vertices P and Q are (3, -4) and (5, -1) respectively.
We are to find the co-ordinates of the vertices P″ and Q″.
Case I : ΔPQR dilated to ΔP'Q'R'
The co-ordinates of P' and Q' are given by
Case II : ΔP'Q'R' dilated to ΔP''Q''R''
The co-ordinates of P'' and Q'' are given by
Thus, the co-ordinates of the vertices P'' and Q'' are (9, -12) and (15, -3).
Option (D) is CORRECT.

19,5/100=0,195................
Perimeter of given figure is equal to :
Perimeter of square - side length + quarter Circumference of the circle
that is :
So, the required perimeter is 37.85 units
I got 105in². When you multiply the two roots, everything goes under one 'roof', and then it's a matter of taking out the perfect squares.
Like: √175 × √63
√(7×5×5) √(3×3×7)
the pairs come out
7×5×3 = 105
Hope that's not toooooo confusing xD
