2\sqrt{15^2}=2\cdot15=30\\\\\\2\sqrt{15^2}=2\cdot\left(15^2\right)^\frac{1}{2}=2\cdot15^{2\cdot\frac{1}{2}}=2\cdot15=30



\left(2\sqrt{15}\right)^2=2^2\cdot\left(\sqrt{15}\right)^2=4\cdot15=60\\\\\left(2\sqrt{15}\right)^2=2^2\cdot\left(\sqrt{15}\right)^2=4\cdot\left(15^\frac{1}{2}\right)^2=4\cdot15^{\frac{1}{2}\cdot2}=4\cdot15^1=4\cdot15=60

GRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
Ulleksa [173]

As the world I’m heading towards and matching up to is getting bigger  

It makes me feel an emptiness somehow  

What part it is, even if the shape is maybe like this  

Even when myself can’t come to know it  

As if solving up the scattered pieces  

We are matching up our stories  

Inside the empty spot in my heart, there’s a piece called you taking place  

I just know it at first glance I saw you  

You’re my missing puzzle piece  

Finally I solved it  

You filled every piece of my heart, even the scarred part of it to the fullest  

And somehow, you’ve become my everything  

My missing puzzle piece  

The fact that I have a flaw,  

The truth that I am imperfect All of it makes me feel small  

But in between those gaps  

We can fill one another with it  

So I don’t even realized that it was empty  

“Hello, it’s been so long, isn’t it?”  

The small piece that I put in my pocket and carry around everywhere  

Please be with me so it can be fuller and prettier  

After I met you, I’m able to draw a bigger picture  

You’re my missing puzzle piece  

Finally I solved it  

You filled every piece of my heart, even the scarred part of it to the fullest  

And somehow, you’ve become my everything  

My missing puzzle piece  

My missing puzzle piece  

More than having everything, Not losing that one thing is more important  

Through you, I came to know that  

You’re my missing puzzle piece  

Very dazzling  

It becomes one scene inside the world that I’ve been trying to put together alone

Like the hands that are interlocking tight together,

Because without you, it can’t be completed  

So that we won’t lose each other,  

My missing puzzle piece

Eli needs pieces of ribbon cut into strips that are 2 1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression cou
Anna71 [15]
Hi there! 2 ½ is equivalent to 2.5 and 7 ½ is equivalent to 7.5. An expression that can be used to find out how many strips can be cut is this:

2.5x = 7.5

This is because the length of the ribbon needed to be cut is 2.5 ft long and we are looking for how many of that length could be cut out of a roll of ribbon that is 7.5ft long. All you have to do for this is divide both sides by 2.5 to isolate the variable. 7.5/2.5 is 3. x = 3. Eli can cut 3 strips of 2½ ft long ribbon.

PLEASE HELP I DONT UNDERSTAND!!
slega [8]

Answer:

see explanation

Step-by-step explanation:

3x and 144 are adjacent angles on a straight line and sum to 180°

3x + 144 = 180 ( subtract 144 from both sides )

3x = 36 ← value of 3x

divide both sides by 3

x = 12

and

2y - 5 and 95 are vertically opposite angles and are congruent, so

2y - 5 = 95 ← value of 2y - 5

add 5 to both sides

2y = 100 ( divide both sides by 2 )

y = 50

Then

x + y = 12 + 50 = 62
