The answer is D. 12+5=17 and 5*12+5=65.
This equation is correct because adult tickets cost five dollars (5 per adult) and childrens tickets cost one dollar (one per child), which need to be added together to get the total.
Answer:
d
Step-by-step explanation:
Circumference= 2×pi×R
Area= pi× R^2
Since Diameter=2 cm ---> Radius is 2× diameter , so R=4 cm
Circumference=2×3.14×4= 25.12 cm
area=3.14× (4)^2= 50.24 cm^2
Let
x-------> the length side of the poster
y-------> the width side of the poster
we know that
Area of the poster is equal to
-------> equation 
Area of the printed area is equal to
----> equation 
substitute equation in equation
![Aprinted=[210]-3x-2*[\frac{210}{x}]+6](https://tex.z-dn.net/?f=%20Aprinted%3D%5B210%5D-3x-2%2A%5B%5Cfrac%7B210%7D%7Bx%7D%5D%2B6%20%20)
using a graph tool
Find the vertex of the graph
The vertex of the graph is the point that represent the value of x for the largest printed area
see the attached figure
the vertex is the point 
the largest printed area is 
find the value of y
therefore
the answer is
The dimensions of the poster are 
Living Room: 16(2x + 3) = 32x + 48
Bathroom: x(x - 1) = x^2 - x
Closet: (x - 1)(x - 1) = x^1 - x - x + 1 = x^2 - 2x + 1
Kitchen: (2x + 3)(x - 2) = 2x^2 - 4x + 3x - 6 = 2x^2 - x - 6
Bedroom: 15(2x - 1) = 30x - 15
