Answer:
9x^2-25=(3x-5)(3x+5)
Step-by-step explanation:
9x^2-25=(3x)^2 - 5^2 =(3x-5)(3x+5)
A^2 - B^2 =(A-B)(A+B)

Answer: The last option.
Step-by-step explanation:
1. By definiton, the rotation rule 90° about the origin is:
(x,y)⇒(-y,x)
2. You know that the coordinates of triangle X'Y'Z' are the following:
X'(-2,2)
Y'(0,6)
Z'(1,1)
3. Now, when you apply the rule, you obtain that the coordianates of the pre-image are the following:
X(2,2)
Y(6,0)
Z(1,-1)
Therefore, the answer is the last option.
