Answer:
D
Step-by-step explanation:
f(x) - g(x) = -9x^2 - 7x + 12 - (3x^2 - 4x - 15) Remove the brackets
f(x) - g(x) = -9x^2 - 7x + 12 - 3x^2 + 4x + 15
f(x) - g(x) = -9x^2 - 3x^2 - 7x + 4x + 12 + 15
f(x) - g(x) = -12x^2- 3x + 27

The answer is B because reread the question
Answer:
b)
Step-by-step explanation:
Question 11:
Isometry is a transformation the preserves the distance and there is no change in the distances. It includes rotation, reflection and translation . Hence the figures are congruent. So the statement is false
Question 12:
A reflection is a transformation where every point of the line is of equal distance from a particular line called the line of reflection
Hence this statement is true
Question 13:
The angle of rotation is the turning of every angle of a figure about a specific fixed point in a specific degree. Hence the statement is true
