Step-by-step explanation:
Follow PEMDAS:
First, distribute 3 to all terms within the parenthesis
3(4x) = 12x
3(5) = 15
12x + 15 + 2
Simplify. Combine like terms
12x + (15 + 2)
12x + 17
12x + 17 is your answer

Answer:
5.2
Step-by-step explanation:
distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.
simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.
