Answer:
B. Polygon ABCD was reflected over the x-axis and then reflected over the y-axis.
Answer:
x = 36
Step-by-step explanation:

Subtract x and 36 from both sides.

Divide both sides by -1.

Square both sides.

Subtract 144x from both sides.

Factor the right side.



Since the solution of the equation involved squaring both sides, we musty check the answer for possible extraneous solutions.
Check x = 36:





Since 0 = 0 is a true statement, the solution x = 36 is a valid solution.

Answer:
x = 2.6
Step-by-step explanation:
To find x, you need to find how many times you need to multiply 25 to get 65. Using reverse operations will make this easier. 65 / 25 = 2.6. We can check this by multiplying 25 by 2.6, and we get 65.
