Answer:
14, 16, 18
sum of the smallest (14) and 3 times the second (16)
14 + 3 x 16 = 62
is 26 more than twice the third (18)
2 x 18 = 36
36 + 26 = 62
For this case we must represent the following expression algebraically:
"eight more than the product of a number and two"
Let "x" be the variable that represents the unknown number
We have to:
the product of a number and two is represented as: 
Then, the full expression will be:

Thus, we use multiplication and addition.

Option C
Answer:
The new volume is two times the original volume
Step-by-step explanation:
we know that
The volume of a rectangular prism

where
B is the area of the base
H is the height of the prism
If the height of a rectangular prism is doubled,
then
The new volume is equal to


therefore
The new volume is two times the original volume
Train 1 = (x) = 357.1 mph
Train 2= (x + 5.9) = 363 mph
