which means the parabola lies above the x-axis over its entire domain. This means the area is given by
C. Jasmine bought some tiles to put around her patio. . .
They asked for area which is always L x W, which was the give away.
The square root of 25 is 5.
Your just trying to find what number you can multiply with its self to make that number. So 5x5 = 25
Another example is lets say 64, the square root of 64 is 8 because 8x8 = 64.
Hope this makes sense!!
Hope this Helps!!
Answer:
We have the next relation:
A = (b*d)/c
because we have direct variation with b and d, but inversely variation with c.
Now, if we have 3d instead of d, we have:
A' = (b*(3d))/c
now, we want A' = A. If b,c, and d are the same in both equations, we have that:
3bd/c = b*d/c
this will only be true if b or/and d are equal to 0.
If d remains unchanged, and we can play with the other two variables we have:
3b'd/c' = bd/c
3b'/c' = b/c
from this we can took that: if c' = c, then b' = b/3, and if b = b', then c' = 3c.
Of course, there are other infinitely large possible combinations that are also a solution for this problem where neither b' = b or c' = c
