Answer:
Step-by-step explanation:
A =adults
C = children
$8*A + $5*C = $76
So there are 4 children
$8*A + $5*4 = $76
$8*A + $20 = $76
$8*A = $76 - $20
$8*A = $56
A = 56/8 = 7
There are 7 adults attending the play.

Step-by-step explanation:
Answer: x^2+29x+39
You would first have to set up an equation, which would be ((2x+9)⋅(x+6))-((x-5)⋅(x-3)) to find the area of both rectangles.
Then you can simplify it, which gives us 2x^2+21x+54-(x^2-8x+15)
Then simplify it even more which gives us 2x^2+21x+54-x^2+8x-15
Then we can get our answer: x^2+29x+39
Hope that helps :)
