Answer:
k=20.
Explanation: First we find where f(x) has its local extrema: f'(x)=3x2−10x+3. The critical points are roots of the equation: 3x2−10x+3=0.
3h - 8h + 10 = 10 - 5h
-5h + 10 = 10 - 5h
infinitely many solutions
1 (B), because 3+-2=1, and 5+-4=1, which amounts to 1/1, or whole number 1.
28 to 42 means 28/42
We now reduce 28/42 to lowest terms.
28 ÷ 7 = 4
42 ÷ 7 = 6
We now have 4/6.
We now reduce 4/6.
4 ÷ 2 = 2
6 ÷ 2 = 3
Final answer: 2/3
A square should have 4 lines of symmetry
