Answer:
width of the rectangular prism = 4.5 inches
Step-by-step explanation:
The volume, V, of a rectangular prism is determined using the formula , where l is the length, w is the width, and h is the height of the prism.
he width, and h is the height of the prism. Carltren solves for w and writes the equivalent equation w =
Volume of a rectangular prism = length * width * height
V= l*w*h
Solve for w. divide both sides by l*h
a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches
4.5= w
So width of the rectangular prism = 4.5 inches

Step-by-step explanation:
To find the determinant of a 3x3 matrix, you can use this method. (See picture.)
Start with the first number in the top row, and block off the row and column. A 2x2 matrix will be left. Find the determinant of this 2x2 matrix, and multiply it by the number in the top row.
Repeat for the other two numbers in the top row. Add the first result, subtract the second, and add the third.
det A = -2 [(3)(-5) − (a)(0)] − 2 [(0)(-5) − (a)(0)] + b [(0)(0) − (3)(0)]
det A = -2 (3)(-5) − 0 + 0
det A = 30
