Answer:
B. 5
Step-by-step explanation:
If you plug the given choices in, -6 and 6 will create undefined answers. A zero in the denominator is always undefined. The only way to get the equation to equal zero would be if the numerator were equal to 0. Which would be 5.
Answer:
6x²-26x+31
Step-by-step explanation:
(x²-3x+5)(2x-7)
=2x³-7x²-6x²+21x+10x-35
=2x³-13x²+31x-35
Now to differentiate:
dx=6x²-26x+31
Distance = root (3-3)²+(2.6-1.4)² = 1.2
the answer is 1.2 units
