Hope this answer helps, it would be 6 since there is 6 sides to a cube.
F(x) = 12x - 3 would look like this graphed.
Hope this helped, you're welcome! :)
Answer:
63
Step-by-step explanation:
Multiply 0.4 by 45 (which is 18) then add that to 45.
F(x) = x^2 +2*7x + 40
.. = (x^2 +2*7x +7^2) +(40 -7^2)
.. = (x +7)^2 -9
f(x) = (x +7)² -9
