Answer:
4.24 to two decimal places
F(2) is same thing as saying x =2
So just plug in 2 for x and solve for x
3*(2)^3 - 12*(2)^2 =
3*8 - 12*4 =
24-48 =
-24
D
Answer:
D) c - 2 = 25 + c + 10√c
Step-by-step explanation:
The given equation is 

Taking square on both sides, we get
Here we used ( a+ b)^2 = a^2 + b^2 + 2ab formula.
c - 2 = 5^2 + (√c)^2 + 2(5)√c
c - 2 = 25 + c +10√c
Answer: D) c - 2 = 25 + c + 10√c
Thank you.
