<h2>Hello!</h2>

The answer is:

The correct option is the second option:

\frac{5}{2},\frac{-1}{2}

<h2>Why?</h2>

We are given the following expression:

\frac{2+-\sqrt{9}}{2}

Now, solving we have:

First solution:

\frac{2+\sqrt{9}}{2}=\frac{2+3}{3}=\frac{5}{2}

Second solution:

\frac{2-\sqrt{9}}{2}=\frac{2-3}{3}=\frac{-1}{2}

Hence, we have that the correct option is the second option:

\frac{5}{2},\frac{-1}{2}

Have a nice day!

Answer:

The correct answer is second option

5/2, -1/2

Step-by-step explanation:

From the attached figure we can see that,

(2 ± √9 )/2

<u>To find the simplified form of (2 ± √9 )/2</u>

(2 ± √9 )/2 = (2 + √9 )/2 or (2 - √9 )/2

(2 + √9 )/2 = (2 + 3)/2 = 5/2

(2 - √9 )/2 =  (2 - 3)/2 = -1/2

Therefore simplified form of (2 ± √9 )/2 are

5/2 and -1/2

The correct answer is option 2

Consider the expression 40+24 . Find the greatest common factor of the two numbers and use the distributive property to rewrite
Margarita [4]

Hi there!

\large\boxed{8(5+3)}}

The greatest common factor of 40 and 24 is 8.

8 goes into 40 5 times:

8 goes into 24 3 times.

We can rewrite this expression for distribution using the amount of times 8 goes into both numbers:

8(5 + 3)

Using this, we get:

8(5) + 8(3) = 40 + 24.
