Step-by-step explanation:
Given the expression 
To simplify the expression, we need to first collect the like terms of the functions in parentheses as shown;

Then we find the LCM of the resulting function

The final expression gives the required answer
Answer:
x= 14
Step-by-step explanation:
x + 5x +10x = 224 CENTS
solving for x
16x = 224
x = 14, the number of each coin there is
Substitute the values in the expression
b-a=3-2=1
answer b-a=1
5 * (2 + 4)
5 * 2 + 5 * 4 (the distributive property)
5 * 6 (order of operations)
A constant because it a number
