Answer:
x^2 + y^2 = a
Step-by-step explanation:
a > or = 36

Why?
We can find the perimeter of any triangle adding the length of its sides. Since we are given 3 points, we need to calculate the length of the three sides of the triangle, and then add them to know the perimeter of the triangle.
Let be the points:
A(-3,-1)
B(-1,2)
C(6,1)
<h3>
- Distances</h3>
From A to B:

From A to C:

From B to C:

Now, calculating the perimeter, we have:

Have a nice day!
Answer:
i think it is false, true, false
Step-by-step explanation:
Answer:
x = 3.53 ft
y - 3.53 ft
z = 3.53 ft
Step-by-step explanation:
given details
volume = 44 ft^3
let cardboard dimension is x and y and height be z
we know that area of given cardboard without lid is given as
A = xy + 2xy + 2yz
xyz = 44 ft^3
To minimize area we have
A = xy + 2x (44/xy) + 2y(44/xy)
A = xy + (44/y) + (44/x)
we have

from 1 and 2

xy(y-x) = 0
xy = 0 or y = x
from geometry of probelem
x ≠ 0 and y ≠ 0
so y = x
x^3 = 44
x = 3.53 ft = y
z = 44/xy = 3.53
