When integers have the same sign and you add them together the sum will have the same sign

7 + 5 = 13
-7 + (-5) = -13

400 people were surveyed about their eye color. 8% of the people surveyed have green eyes. how many people had green eyes

VashaNatasha [74]

Answer:

Step-by-step explanation:

The problem above can be solved by using the multiplication operation.

Given: 400 people

8% of the people with green eyes

Let's solve:

Let x be the number of people with green eyes.

x = 400 x 8%

x = 400 x (0.08)

x = 32

So, the number of people surveyed with green eyes is 32. The rest of the surveyed people (368) have a different eye color.

Factoring by grouping x^2 + 4y + 2x + 2xy pls explain with work too!!!

Gennadij [26K]

${x}^{2} + 4y + 2x + 2xy$

We can factorise this expression by grouping. First let us arrange it in this way

$= {x}^{2} + 2xy + 2x + 4y$

Let us bracket them like this:

$= ( {x}^{2} + 2xy) + (2x+ 4y)$

In the first bracket portion, take x as common and in the second expression, take 2 as common.

$= x(x + 2y) + 2(x + 2y) \\ = (x + 2)(x + 2y)$

Answer:

$(x + 2)(x + 2y)$

Hope you could understand.
