That is true. Since the area of a triangle is 1/2bh the b and h don't change if the triangles are the same
Answer:
The radius of the circle is 
The length of the square is 
Step-by-step explanation:
we know that
The circumference of a circle is equal to 
The perimeter of the square is equal to 
so

Simplify

-----> equation A
The area of a circle is equal to 
The area of a square is 
The total area is equal to
-----> equation B
substitute equation A in equation B
![At=\pi r^{2}+[(12-\pi r)/2]^{2}](https://tex.z-dn.net/?f=At%3D%5Cpi%20r%5E%7B2%7D%2B%5B%2812-%5Cpi%20r%29%2F2%5D%5E%7B2%7D)
This is a vertical parabola open upward
The vertex is the minimum
The x-coordinate of the vertex is the radius of the circle that produce a minimum area
The y-coordinate of the vertex is the minimum area
Solve by graphing
The vertex is the point (1.68, 20.164)
see the attached figure
therefore
The radius of the circle is

Find the value of x

assume



Replace x with the possible answers and solve to see which ones make the equation true:
5(3) = 15 + 4 = 19. 19 is < 29 so 3 works.
5(4) = 20 + 4 = 24. 24 is < 29, so 4 also works.
5(5) = 25 + 4 = 29. 29 is not less than 29 so doesn't work.
Only 3 and 4 will work.
The answer would be {3,4}
Answer:
m=1
Step-by-step explanation:
add 6 to both sides, 9=9m
divide 9 on both sides, m=1
