Answer:

x = 4

Step-by-step explanation:

110ₓ = 40₅ --------- change all to base ten.

the system called binary

1x²+1x ¹+0x⁰ = 45¹+0*5⁰

x² + x + 0 = 20

x² + x – 20 = 0

solve x using Quadratic equation

-1 ± $\sqrt{1^2 - 4* 1 (-20)}$

x = ------------------------------------

2 * 1

x = -5; x = 4

therefore, x = 4

What's the inverse of a 2x4 matrix?

balandron [24]

Mxn Matrices do not have an inverse solution for m ≠ n, so your 2x4 will not have a solution.

Generally, inverting matrices is done through finding the determinant of the square matrix and then performing an operation on the matrix based on the size of the matrix. 

Wikipedia has a good article on Matrix inversion, take a look there for more information.
