What is that product of 2x + y and 5x -y + 3

poizon [28]

Answer:

10x² + 6x + 3xy + 3y - y²

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, as shown

(2x + y)(5x - y + 3)

= 2x(5x - y + 3) + y(5x - y + 3) ← distributing

= 10x² - 2xy + 6x + 5xy - y² + 3y ( collect like terms )

= 10x² + 6x + 3xy + 3y - y²

The owner of a new restaurant wants to have seating for more than 75 people. There is currently a

Fudgin [204]

Answer:

$4m+3>75$

Step-by-step explanation:

Given:

Number of people to be seated should be greater than 75.

Let $n$ be the number of people. So,

$n > 75$

Now, there is a single private chef's table that can seat 3 people.

Tables bought by the owner = $m$

Number of people seated in 1 table = 4

So, number of persons that can be seated in $m$ tables = $4\times m=4m$

Now, total number of persons that can be seated in these two types of tables is the sum of 3 and $4m$

Therefore, $n = 4m+3$

But, $n>75$

Hence, the inequality to show the situation is:

$4m+3>75$
