Answer:
1680 ways
Step-by-step explanation:
In this question, we are tasked with finding the number of ways in which we can select 4 trips out of 8 to make today.
Let us label the the trips we are to select as A B C D, one after the other
For selection A, we have 8 different trips waiting to be selected
For selection B, we have 7 trips to select from
For C, we have 6 to select from
while for D, we have 5 to select from. Thus, the total number of ways in which we can select these trips can be calculated as = 8 × 7× 6× 5 = 1,680 ways

Answer:
15
Step-by-step explanation:
input each of the values (g=9 and h= -14) and solve then add them together
g(9) = 14 - 2/3 (9)
14 - 18/3 (or 6) = 8
h(-14) = -(-14) - 7
14 - 7 = 7
8 + 7 = 15
