567 = 500+60+7
4*567 = 4*(500+60*7)
4*567 = 4*500 + 4*60 + 4*7 ... see note below
4*567 = 2000 + 240 + 28
4*567 = 2268

note: multiply the outer term 4 by each term inside the parenthesis to use the distributive property. The general distributive property is a*(b+c) = a*b+a*c. This can be extended to a*(b+c+d) = a*b+a*c+a*d. You can have as many terms as you like inside the parenthesis.
Answer:
The answer is B) $110.50 for 6.5 hours of work
Step-by-step explanation: Divide 119.00/7. This equals 17. To find anything equivalent to this, divide the amount of money earned by the hours worked. Starting from A, you divide 120.50 by 8.5. This equals 14.1764706... This clearly isn't equivalent. Then you move downward to option B. Here, you divide 110.50 by 6.5. This then gives you 17. As you can see, it is equivalent to the rate that the printer earns; therefore, this is the only option.
X^2+10x+16＝0
First, you find factors of 16.
1 x 16
2 x 8
4 x 4
Next, you find which of the factor pairs adds up to 10 (from the 10x). In this case, 2 x 8 because 2 times 8 is 16 and 2 plus 8 is 10.
Then, the equation will be written out as: (x+2) (x+8). Take those two equations and set them equal to 0, and then solve.
x+2＝0
-2 -2
x＝-2
x+8＝0
-8 -8
x＝-8
So, your answers are x＝-2 and x＝-8. You can check by plugging in those two numbers as x.
