HI there i know this is way later than you needed it but I though i would give you the correct answer which is B x=±√15/3 i also have proof from an old test that my answer is right.
3x³×y²×12x²×y×z=36x⁵×y³×z
B. This quadratic is a negative on the y axis
What is it you need help on?
or "helph" in fact.
Answer:
20 feet.
Step-by-step explanation:
Pythagoreans theorem states that a^2 + b^2 = c^2
a = 12, squared = 144
b = 16, squared = 256
144 + 256 = 400
√400 = 20
20 feet is the answer.
Hope this helps.
