1:2
Looking at the image, there are 2 grey squares and 1 black square. Since the question is asking how many black squares to grey squares, it would be a 1:2.
Answer:
f(x) = (x + 3)² - 14
Step-by-step explanation:
f(x) = x² + 6x - 5
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
f(x) = x² + 2(3)x + 9 - 9 - 5
= (x + 3)² - 14 ← in vertex form
The answer is b 14 , every 4 months, 200$ is saved if at 12 months he has saved 700$ we know that it will take another 2 months to save 100$ so its 14
There are 6 balls to every box (a ratio of 6 to 1). Therefore, when there are 78 balls, there are 13 boxes.
