Answer:
f(-2) = 4
Step-by-step explanation:
f(x) = x²
f(-2) = (-2)² = (-2)(-2) = 4
Let x represent the middle one. Then the largest is x+2; the smallest is x-2.
(x+2) +2(x-2) = 25
3x = 27 . . . . . . . . . . simplify, add 2
x = 9 . . . . . . . . . . . . divide by 3
The integers are 7, 9, 11.
Answer:
Divide 250 by 9.4 to get 26.6
Step-by-step explanation:

Answer: There will be about 888,915 gallons of water left in the spherical tank
Now, multiply that by 7.5 and you will have 1,028,915 gallons of water in the tank.
Finally, just subtract the 140,000 gallons and we are at our answer.
Hope this helps!
Idk if I can simplify that
