The answer would be 21 good luck hope you get it correct
D would me the answer I just took the assignment
D = vt
Distance traveled by train
d = 55t
Distance traveled by plane
d = 285t
Total distance
d = 1020
So, you do:
distance traveled by plane + distance traveled by train = total distance
(55t) + (285t) = 1020
Solve for t
t = 3 hours
t is the time traveled by each so 3 hrs traveled by train and 3 hrs traveled by plane
Total time = 3 + 3 = 6 hours
Answer:
distributive

you are distributing 5(d+1) into 5d +5
Answer:
All real values of x where x < −1.
Step-by-step explanation:
There is a turning point at x= 1 and f(x) = -4 and it open upwards.
So it decreases for all real values of x where x < 1. But it passes through the point (-1, 0) after which the values of the function become negative.
So the answer is all real values where x < -1.
