Answer:
x = 7
Step-by-step explanation:
Using Cramer's rule, the value of x is ...
x = ((2)(-2) -(22)(3))/((-1)(-2) -(4)(3)) = (-4-66)/(2-12) = -70/-10
x = 7
The side length is six units.
A cube has three measurements: length, width, and height
All the measurements have to be the same.
This allows you to cube root.
The cube root of 216 is 6.
The side length of the cube is 6 units.
Check:
6 * 6 * 6 = 216.
It is correct, so our answer is proven to be correct.
Answer: The volume of the tent is 293.33 ft.
Explanation: 11 x 10 x 8 = 880
The formula for the volume of a right rectangular pyramid is lwh/3.
880/3 = approximately 293.33
The answer is 343
Because volume is length x width x height which would be 7 x 7 x 7
Answer:
1 + i
Step-by-step explanation:
Given that A is a 3 * 3 singular matrix
one of its eigenvalue ( λ1 ) = 1 - i
Given that the determinant of a singular matrix is = 0
therefore the second eigen value ( λ2 ) = 1 + i
1 - i + 1 + i = 0
