Answer:Because its -2x exponent of 2 so you cant do anything to that but you can touch the 2x it doesn't have a exponent so that's why but now since you did something to 2x you have to change 2x exponent of 2 into negative
Step-by-step explanation:
2x² + 2x + ? = x
⇒ ? = x - 2x² - 2x
⇒ ? = -2x² - x
Your answer is incorrect because 2x² - x² would mean x² is part of the answer, which is clearly incorrect.
Answer:
c
cost = 112
profit= 168
280÷100=2.8
2.8×40=112
profit = price - cost
= 280-112
= 168
x= 105/4
x=4
y = 15x + 20
He charges a flat rate of $20, so any total for hours worked will have an additional $20 added to it.
The 15x represents his earnings per hour. He makes 15 per every hour worked, x represents the number of hours worked
