Answer:to Let f(t) = 6, g(t) = −5t, and h(t) = 2t2
Step-by-step explanation:
The answer would be "Nine students each make 2 models of Mars and its moons. How many models did they make in total?" Since the answer is 18 and there are 9 students (and also since 18 can be divided into 9), you can divide 18 and 9 to get 2. This makes sense because if each student makes 2 models (as stated), there'd be a total of 18 models (as stated in the question you gave). Hope this helped!
Since 20 is a factor of 40, the least common denominator of 3/20 and 9/40 is 40.
Additive inverses combine to get 0. So, k is -1.4. The sum is 0. Hopefully that will help.
