Answer:
The scale factor of the sides of the Octagon is 2:5
Step-by-step explanation:
Both these octagons can be considered as the combination of 8 similar triangles joined edge to edge.
We know this property of similar triangles, that the ratio of area of similar triangles is proportion to the square of the ratio of sides of the similar triangle.
From the above property, we plug in the values
Therefore, the ratio of the sides of the Octagon are 2:5.

Answer:
B. y = -4x + 15
C. 16x + 4y = 9
D. y=-4X
Step-by-step explanation:
Two lines are parallel if they have the same slope. The equation of a line is:
y = mx + b
Where m is the slope and b is a constant.
So, the slope of the first equation can be calculated solving the equation for y as:
8x + 2y = 7
2y = - 8x + 7
y = -4x + 7/2
So, the slope is -4.
It means that all the equations that could represent lines that could also be drawn for his art project are the equation with a slope equal to -4.
Then, for every option, we get:
A. y-1 = 4(X + 8)
y = 4x +32 +1
The slope is 4
B. y = -4x + 15
The slope is -4
C. 16x + 4y = 9
4y = -16x + 9
y = -4x + 9/4
The slope is -4
D. y=-4X
The slope is -4
E. 4x + 2y = 3
2y = -4x + 3
y = -2x + 3/2
The slope is -2
Finally, the equations that are parallel to the line 8x + 2y = 7 are equations B, C and D
