( x - 3i√2)(x + 3i√2)
solve x² + 18 = 0
x² = - 18 ⇒ x = ±√- 18 = ±3i√2
factors are ( x - (3i√2))(x - (-3i√2))
x² + 18 = (x - 3i√2)(x + 3i√2)
Answer:
Divide the total cubic yards by the width and height
Step-by-step explanation:
288 / 4 = 72
72 / 8 = 9
Length = 9
The final score in the video game is 67.
Step-by-step explanation:
Points earned = 50 points, 87 points
Points lost = 40 points, 30 points
Let,
Plus sign (+) represent the points earned.
Negative sign (-) represent the points lost.
Therefore,
Points earned = +50, +70
Points lost = -40, -30
Adding all the points to get final score;
Final score = 50+(-40)+87+(-30)

The final score in the video game is 67.
