A) f(x)=0.2x
B)f(12)=0.2(12)=2.4 dollars
Answer: The required product is 
Step-by-step explanation: We are to find the product f the following two algebraic expressions:

To find the product of the above two expressions, we must multiply each term of the first expression with each term of the second expression.
The multiplication is as follows:

Thus, the required product is 
Answer:
y-x
Step-by-step explanation:
I assumed you meant that you wanted me to rewrite the expression without the absolute value signs. Since the absolute value of a number will be the same whichever way you place the numbers, you can rewrite |x-y| as y-x, as x is less than y.
<span>223 degrees
To find the missing angle, you first have to add up all the numbers you know. So 125, 132, 148, 124, 122, 106 and 100 degrees add up to 857 degrees.
We know that the total degrees of an octagon is 1080 degrees, so to find the last number, we would simply do 1080 minus 857 which is 223 degrees.
