Answer:

Step-by-step explanation:
The given matrix addition is

We need to find the elements of matrix B.
Let 
Substitute the value of matrix.

After addition of two matrix we get

On equating both sides.






Therefore, the elements of matrix B are
.
Answer:
x = 15
Step-by-step explanation:
angles 2 and 4 are supplementary so they add up to 180
2x + 10 + 4x + 80 = 180
6x + 90 = 180
6x = 90
x = 15
Responder:
120 maneras.
Explicacion paso a paso:
Cinco tipos diferentes de semillas.
El numero de formas de organizar, n, a diferencia de los objetos en una linea es n!
Entonces, para sembrar 5 tipos diferentes de flores, serian 5!
5! = 5 * 4 * 3 * 2 * 1 = 120 vias.
Por lo tanto, hay 120 formas de sembrar las cinco semillas.

When working with very large or very small numbers, scientists, mathematicians, and engineers use scientific notation to express these quantities. Scientific notation is a mathematical abbreviation, based on the idea that it is easier to read an exponent than to count many zeros in a number. Very large or very small numbers need less space when written in scientific notation because the position values are expressed as powers of 10. Calculations with long numbers are easier to do when using scientific notation
The next smaller tenth is 29.3 .
The next bigger tenth is 29.4 .
29.34 is nearer to 29.3 than to 29.4 .
So the nearest tenth is 29.3 .
