I would say the way to figure out this answer is to find out what two numbers make a sum, difference, product, dividend of 6 and and from the choices I exampled I think you would have to use inverse of operation but it depends if you are equations

I'm not sure either but I tried, Have a great day:), ~Nana!~

Here is a less obvious example of a linear function. Imagine putting a rope around the Earth. Make it nice and snug. Now add 33

cluponka [151]

Answer:

A person who has height less than 5.2521 m can walk under the rope without hitting his/her head.

Step-by-step explanation:

Radius of earth = R

Length of rope around Earth = Circumference of Earth = 2πR

Now add 33 m to the length of the rope that means to increase the circumference

C = 2πR+33

Now,

C = 2πR'

⇒2πR' = 2πR+33

In order to find the height we need to find difference of the radii

⇒2πR'-2πR = 33

$\\\Rightarrow R'-R=\frac{33}{2\pi}\\\Rightarrow R'-R=5.2521\ m$

So, a person who has height less than 5.2521 m can walk under the rope without hitting his/her head.

Which of the following expression cannot be factored out using difference of two square

Ratling [72]

Answer:

Step-by-step explanation:

Factoring using difference of squares

a² - b² = (a - b)(a + b)

x² - 1

= x² - 1²

= (x - 1)(x + 1)

x² - y²

= (x - y)(x + y)

x² - 4

= x² - 2²

= (x - 2)(x + 2)

4 - 16y ← 16y is not a perfect square and so cannot be factored

If it was 4 - 16y² then it could be factored using difference of squares
