Answer:  The required product is 10x^2-y^2+3xy+6x+3y.

Step-by-step explanation:  We are to find the product f the following two algebraic expressions:

E_1=2x+y,\\\\E_2=5x-y+3.

To find the product of the above two expressions, we must multiply each term of the first expression with each term of the second expression.

The multiplication is as follows:

M\\\\=E_1 \times E_2\\\\=(2x+y)\times(5x-y+3)\\\\=10x^2-2xy+6x+5xy-y^2+3y\\\\=10x^2-y^2+3xy+6x+3y.

Thus, the required product is 10x^2-y^2+3xy+6x+3y.

Answer: 10x^2-y^2+3xy+6x+3y

Step-by-step explanation:

Given expressions are 2x+ y and 5x -y +3

Product of 2x+y and 5x-y+3 is

(2x+y)\times (5x-y+3) = 2x\times (5x-y+3) + y\times (5x-y+3) ( by applying distributive property under multiplication over addition)

⇒(2x+y)\times (5x-y+3) = 10x^2-2xy+6x+5xy-y^2+3y (again by distributive property)

⇒(2x+y)\times (5x-y+3) = 10x^2-y^2+3xy+6x+3y  ( by operating the like terms.)

Canceling units is also called: a. changing the value c. multiplication b. unit analysis d. making connections
SOVA2 [1]

Canceling units is also called unit analysis.

This is also called dimensional analysis.

What is a unit of analysis in statistics?

  • The unit of analysis is the entity that you're analyzing. It's called this because it's your analysis (what you want to examine) that determines what this unit is, rather than the data itself.
  • Because it is the analysis you do in your study that determines what the unit is.
  • For instance, if you are comparing the children in two classrooms on achievement test scores, the unit is the individual child because you have a score for each child.

For example -

1 ft = 12 in

3 ft =  3 ft * \frac{12 in }{1 ft}

3 ft = ( 3 * 12 )  in ⇒ 36 in
