Assuming this, you have to start by writing two equations from the information provided:
180 total tickets were sold
x+y=180
they made $590 and adult tickets cost $4 and kids tickets cost $2
180=4x+2y
lets solve for x in the first equation:
x=180-y
we can plug this into the second equation and solve for y
590=4(180-y)+2y
590=720-4y+2y
590=720-2y
-130=-2y
y=65
we can plug this into the first equation and solve for x:
x+65=180
x=115
I hope this helps.
Answer: An is n+1 and A10 is 4
Step-by-step explanation:
The question is very vague and hard to answer. so A1 is -5, count up by 1 ten times, including -5, so -5, -4, ..., 3, 4. An is a just the way it changes, so it adds by one every time.
Hope this helps, it is a very vague question tho.

Step by step explanation:
The equation in the form (x + a)² = b is (x + 2)² = 16
<h3>How to determine the intermediate step?</h3>
The equation is given as:
x² + 4x = 12
Take the coefficient of x
k = 4
Divide by 2
k/2 = 2
Square both sides
(k/2)² = 4
Add this result to both sides of x² + 4x = 12
x² + 4x + 4 = 12 + 4
Evaluate the sum
x² + 4x + 4 = 16
Express as a perfect square
(x + 2)² = 16
Hence, the equation in the form (x + a)² = b is (x + 2)² = 16
