1) The dependent variable is the total cost.
2) The perimeter is 36 inches.
The dependent variable is the one that gets changed by the other one. In this case, the total cost gets changed by the amount of fabric bought.
To find the perimeter:
Since the ratios of the side length to perimeter is the same, we set up the ratio:
2/8 = 9/x
Cross multiply:
2*x = 8*9
2x = 72
Divide both sides by 2:
2x/2 = 72/2
x = 36

Answer:
A = 
Step-by-step explanation:
given,
Matrix =
A = 
determinant of matrix
|A| = a×a - (a-4)(a+4)
|A| = a² - a² +16
|A| = 16
inverse of the matrix
to calculate inverse of two matrix interchange the term a₁₁ with a₂₂ and multiply the -ve with a₁₂ and a₂₁
the inverse is
A =
A <span> regular </span>icosahedron<span> is a 3D convex polyhedron with 20 faces, 30 edges and 12 vertices while a regular octahedron has 8 faces. A tetrahedron has 4 faces and is shaped like a pyramid. All of these have triangular bases. A regular hexahedron has six faces and a base of a square</span>
