Step-by-step explanation:
2(5)^3 - 4(1)^2
250 - 4
246
Answer:
B.
no real solutions
Step-by-step explanation:
2(x + 11) + 5x = 7x - 22
Distribute
2x+22 +5x = 7x -22
Combine like terms
7x +22 = 7x-22
Subtract 7x from each side
7x-7x+22 = 7x-7x-22
22 = -22
This is never true so there are no solutions
F(x)=3x2-11
f(5)=6-11
5f=-5
5f/5=-5/5
f=-1
