Solve 8 = 2x + 4.
X = -4
X=-1
x = 0
X=7

x = -1

Step-by-step explanation:

Write it in exponential form, 2^3 = 2^x+4

Since base is the same, Set the exponents equal, 3 = x + 4

Move the terms, variable goes to the left side and change the sign -x + 3 = 4

Subtract and calculate, -x = 1

Change the signs on both sides, x = -1

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!
