Answer:
Step-by-step explanation:
Key to this method is remembering that
So, if you divide the coefficient of x by 2 and square it, that will complete the square. With that in mind, things are easy.
6/2 = 3, so add 
So, c=9
Similarly, for the other two,
You don't really have to worry about the sign, since squaring will always make it positive
Answer:
3.2 x 10^13
Step-by-step explanation:
(8x10^4)(4x10^8)
reorder the terms using the commutative property
(8x4)x(10^4x10^8)
multiply
32x (10^4 x 10^8)
= 32 x 10^4+8
= 32 x 10^12
now convert to scientific notation
=3.2 x 10^13
You most likely will win a token. you have the advantage as the most they can win is 1 token if you lose, but you can win 3 tokens.
Answer:
0 - 20
1 -22
5 - 30
10 - 40
15 - 50
20 - 60
Step-by-step explanation:
The initial amount this equation is 20 so that is why at 0 shirts its still 20 dollars for the set up fee and 2 dollars per shirt. Now that we have this information we can actually make a linear equation
y = 2x + 20
y = the total cost
x = the number of shirts
All you have to do next is plug in the number of shirts to get the total cost
Example: 2(1) + 20 = y
2 + 20 = y
22 = y
Meaning for 1 shirt it would be 22 dollars in total
