Answer:
Step-by-step explanation:
First multiply 2x - 5 by 3 amd will open the brackets
3(2x-5)-4=33
6x - 15 - 4 = 33
6x - 19 = 33
Take -19 to other side and its sign will be become +
6x = 33 + 19
6x = 52
x = 8.6
If you mean A*B, then yes since,
number of columns in matrix A = number of rows in matrix B
ie the inner dimensions both match up (both are 3)
However, B*A is not defined
When there is a negative in squre root, it means imaginary number come in. 'i' is usually the varible used to identify imaginary numbers.
First remove the negative from the square root and find the square root of 4, which is 2. Then add i to 2. 2i
Now solve for the positive then negative.
-2 + 2i
----------- = -1 + 1i
2
-2 - 2i
----------- = -1 - 1i
2
Both -1 + 1i and -1 - 1i are the answers.
Answer:
x= -1/6
Alternative form:
x= -0.16, x= -6^-1
