Answer:
x = -6 ±sqrt(251)
Step-by-step explanation:
3(x+6)^2=753
Divide each side by 3
3/3(x+6)^2=753/3
(x+6)^2=251
Take the square root of each side
sqrt((x+6)^2)=±sqrt(251)
x+6 = ±sqrt(251)
Subtract 6 from each side
x+6-6 = -6 ±sqrt(251)
x = -6 ±sqrt(251)
Answer:
a³-b³=(a-b)³+3ab(a-b)
or

:/
Answer:
12.5
Step-by-step explanation:
I just know the answer
B.
The median increases less than the mean increases.
W - 2 = -3
