Complete the square.


Use de Moivre's theorem to compute the square roots of the right side.


Now, taking square roots on both sides, we have


Use de Moivre's theorem again to take square roots on both sides.

Answer:
number 3
Step-by-step explanation:
Answer:
B' = (-2,2)
Step-by-step explanation:
So to solve this you need to find the current coordinates of B.
B = (-5,4)
So it says the translation is (x+3, y-2)
Let us substitute in the values
(-5 + 3, 4 - 2)
So the new coordinate is
(-2,2)
Answer:
99
Step-by-step explanation:
5x=45
x=45/5=9
5x+5x+x=11x=11*9=99
