What is the product of 2x + y and 5x – y + 3? x2 + xy + x + y2 + y

miskamm [114]

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

Step-by-step explanation:

You need to remember the Product of powers property:

$(a^m)(a^n)=a^{(m+n)}$

Then, knowing this property, now you have to apply the Distributive property. So:

$(2x+y)(5x-y+3)=\\\\=(2x)(5x)-(2x)(y)+(2x)(3)+(y)(5x)-(y)(y)+(y)(3)\\\\=10x^2-2xy+6x+5xy-y^2+3y$

Finally, to simplify this expression, you need to add the like terms.

Therefore, you get that the product is:

$=10x^2+3xy+6x-y^2+3y$

mezya [45]

There are 150 students in Hannah's school.

Sum of books donated by the students =b.

Average books donated by each student = $\frac{b}{150}$

It is given Hannah donated 3 times as many books each student donated.

Number of books donated by Hannah= $3 times \frac{b}{150} = \frac{b}{50}$

The expression of the number of books donated by Hannah= $\frac{b}{50}$
