Given quadratic equation : 
Let us apply standard quadratic form 
We know, quadratic formula
a = 4
b = 2
c= -1
Now we plug in all the values in quadratic formula
.
<h3>The above one is the substitution of values of a,b,c in quadratic formula.</h3>
The answer is 93. its very simple to round well mosly for me cause im smart
|x + 2| < 4
As neither x or 2 are negative, the bars do not matter and can be eliminated.
x + 2 < 4
Minus 2 from both sides, and because you subtracted, make sure to turn the 'less than' sign into a 'greater than' sign.
x > 2 is your answer

hi im not sure it's right it was kinda confusing
Answer:
cheeseburger is $3 and chips is $0.75
Step-by-step explanation:
Let price of cheeseburger be x while price of a bag of chips be y hence for the case of Nathan, we can write the equation as x+y=3.75. Similarly, for Jack, we can write it as 2x+3y=8.25
x+y=3.75 hence x=3.75-y and substituting this into the second equation we have
2x+3y=8.25
2(3.75-y)+3y=8.25
7.5-2y+3y=8.25
y=8.25-7.5=0.75
x=3.75-y=3.75-0.75=3
Therefore, price of cheeseburger is $3 and chips is $0.75
