The answer would be D) dilated by a scale factor of 3
Proof :
A is at (-2, 1), A' is at (-6, 3) Try multiplying -2 by 3 = 6, 1 x 3 = 3.
I hope this makes sense and helps.
9x^2 - 14x + 20x^2
= 9x^2 +20x^2 -14x
= 29x^2 -14x
Given:
and
.
To find:
Whether
is possible or not.
Solution:
We have,

(CPCTC)
...(i)
And,
...(ii) (Vertically opposite angles)
From (i) and (ii), we get
...(iii)
Now,
(Linear pair)
(Using (iii))


Divide both sides by 2.


The measure of angle 1 is 49 degrees so it cannot be equal to 47 degrees.
Therefore, the required answer is "no", the given statement
is not possible.
