The answer is about 78.540
Answer: -2(x²+22x+40)
Step-by-step explanation:
When you factor an expression, you are taking out a common factor between the terms. A common factor we can take out is -2 or 2.
-2(x²+22x+40)
2(-x²-22x-40)
Both of these answers work, but we can also take out a -1, therefore, our factor is -2(x²+22x+40). Also, it looks nicer with more positive terms than negative.
Jon earns 6 dollars per hour.
We know this because, if he gets paid $20 and buys $2 worth of gasoline, his profit is $18.
Then, we divide 18 by the number of hours he worked, 3, and thus, Jon earns $6/hr.
Answer:
x = 12
Step-by-step explanation:
The 2 given angles form a straight angle and are supplementary, thus
10x - 20 + 6x + 8 = 180
16x - 12 = 180 ( add 12 to both sides )
16x = 192 ( divide both sides by 16 )
x = 12
