Answer:
<h2>B. 3x+3y=8 4x-2y=10 </h2>Step-by-step explanation:
The choices for this question are
A. 3x+3y=8 4x-2y=5
B. 3x+3y=8 4x-2y=10
C. x+y=8 2x-y=5
D. 9s+9y=22 18x+9y=45
Among the options, the system that has the same solutions than the given system is B., because as you can observe such system has the same equations, the first one is the same equation 3x+3y=8, and the second one is the same equation with a factor applied, if we divide such equation by two, we would have
As you can observe, we get the same second equation that it's included in the given system
So, we can conclude that the system B, and the given system are the same, therefore they have the same solutions.

Answer:
91+14π
Step-by-step explanation:
The question is incomplete. Find the complete question attached.
From the diagram shown;
It contains 4 quarter circles which is equal to a circle.
Perimeter of a circle = 2πr
r is the radius = length of one side of the square =7
Perimeter of the circle = 2πr
Perimeter of the circle = 2π(7)
Perimeter of the 4 quarter circles = 14π
Also in the diagram, there are 13 sides of the square present.
Perimeter of the squares = 13×length of one side of the square (Sum of all the sides)
Perimeter of the squares = 13×7 =91
Perimeter of the figure = Perimeter of the 4 quarter circles + Perimeter of the squares
Perimeter of the figure = 91+14π
