X=−1+√17 or x=−1−√17 is the answer.

First get the equation to equal 0 by subtracting 17 from both sides.
You should have x^2+2x-16=0
Next plug your numbers into the quadratic formula(-b^2+/- the square root of b^2-4ac -all divided by 2a)
The end result should be x=-1+/- the square root of 17 or(if you want the decimal) 3.12310562, -5.12310562

Answer:

A. 4

Step-by-step explanation:

First, we can try the first option. 2/4 is equivalent to 6/12 when you multiply the fraction by 3 to get a common denominator. Since 6/12 is larger than 4/12, and the question has 1 answer, 4 is the only value that satisfices the statement and is the answer.

Need Help With This​
gregori [183]

Answer/Step-by-step explanation:

Let x = 4 (you and 3 friends)

Ticket cost per head = $5.50

Drink cost per head = $2.50

Popcorn cost per head = $4.00

<em>Expression representing total amount of money spent = $5.50(x) + $2.50(x) + $4.00(x)</em>

<em />

Evaluate the expression by plugging in the value of x = 4

Total amount of money spent = $5.50(4) + $2.50(4) + $4.00(4)

= $22 + $10 + $16 = $48

<em>Total amount of money spent = $48</em>
