Answer:
= 13x - 1
Step-by-step explanation:
(3x - 2)*2 + 7x + 3
= 6x - 4 + 7x + 3 (using distribution)
= 13x - 4 + 3 (combine similar x terms)
= 13x - 1 (combine all other similar terms)
D 20 units
I know this because 7+7=14 and 3+3=6. Then 6+14=20.

Answer:
Q(18) is a mathematical representation of the weight in pounds of a puppy after 18 months.
Q(30) = 27.5 ; This means that the weight of puppy after 30 months will be 27.5 pounds
Step-by-step explanation:
Given the expressions :
Q(18)
Q(30) = 27.5
Function Q gives a puppy's weight in pounds as function of its age in months
What does each expression represent in this situation?
A function is generally represented in the form a(x) ;
Hence, Q(18) is a mathematical representation of the weight in pounds of a puppy after 17 months
Q(30) = 27.5 ; This means that the weight of puppy after 30 months will be 27.5 pounds. 27.5 is the result of working out the function Q at 30.
