Answer:

When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5). This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).

Step-by-step explanation:

lol it’s on wassa name ;) mark me brainliest? Btw

Here you go, your equation should look a lot like this:

x²-16 -----> (x+4)(x-4).

The bearing of a from b is 067 degrees. what is the bearing of b from a?

Zigmanuir [339]

In this case since 067 is less than 180, 180 will be added to it to find the bearing of b from a.
067+180=247
the bearing of b from a is 247
or
subtract 067 from 360
360-067=293
I am not sure of the right answer but I hope this helps.

One condition for performing a hypothesis test is that the observations are independent. Marta is going to take a sample from a

AleksandrR [38]

Answer:

The correct answer to the following question will be "60 students".

Step-by-step explanation:

Marta will be taking a sampling frame from some kind of 600 student group.

Mean,

N = 60

Although the sampling method could perhaps consist of the following components 10% of the population,

⇒ $600\times 10 \ percent$

⇒ $60$

In order to view these findings as autonomous, 60 students would then have to analyze Marta lacking replacements.

Identify the Terms, Constants, Coefficients and Variables in the following eqaution:

irinina [24]

Answer:

<h2>13x - 1. Term</h2><h2>5y - 1. Term</h2><h2>13 - 3. Coefficient</h2><h2>2 - 2. Constant</h2><h2>5 - 3. Coefficient</h2><h2>y - 4. Variable</h2><h2>3 - 2. Constant</h2><h2>x - 4. Variable</h2>

Step-by-step explanation:

<h3>13x + 5y - 2 = 3</h3><h3 /><h3><u>Term</u> has a <em>number and also a variable</em>. </h3><h3>Ex.: 5y</h3><h3 /><h3><u>Constant</u> is any <em>number without a variable</em>.</h3><h3>Ex.: 3</h3><h3 /><h3><u>Coefficient</u> is the <em>number in a term</em>.</h3><h3>Ex.: 13</h3><h3 /><h3><u>Variable</u> is any <em>letter</em> in the equation.</h3><h3>Ex.: x</h3><h3 />
