Irrational numbers:
π√4 & π√25/4
Now, what is an irrational number ?
It's a number with infinite digits after the decimal point. It can't be expressed as a fraction.
Your friend,

Answer:
y = 4x - 5
Step-by-step explanation:
for slope intercept form
y = mx + c
where m is the slop so
M = 4
point = (1, -1)
a point on the line must satisfy the equation so replacing y and x by -1 and 1 respectively to get to c.
-1 = 4 × 1 + c
-1 - 4 = c
-5 = c
placing these values in y = mx + c
y = 4x - 5
3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.
Step-by-step explanation:
<u>DATA:</u>
Length of strips Eli need is 2.5 feet long
Length of roll of ribbon is 7.5 feet long
Number of strips that can be cut from the 7.5 feet long roll is x
<u>SOLUTION:</u>
To determine how many strips can be cut, divide total length of roll of ribbon by the length of strips needed.
Number of strips that can be cut = 
x = 
(expression)
x = 3 strips
Therefore, 3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Here is the solution...
Compensation
The compensation is nothing but the process of reforming the given expression to find the answer mentally.
Here we need to rewrite the given expression in order find the answer mentally.
<u>Step 1:</u>
Here we can add 8 with 6572, so we get 6580.
<u>Step 2: </u>
Add 8 from 239, so we get 247.
<u>Step 3:</u>
We can rewrite 247 as 240 + 7
<u>Step 4:</u>
Now we can subtract 240 from 6580, so we get 6340.
We can calculate this mentally.
<u>Step 5:</u>
Finally, we can subtract 7 from 6340 mentally, So we get
6333.
Mathematically, the above expression written as
6572- 239
= 6572 + 8 - (239 + 8)
= 6580 - 247
= 6580 - (240 + 7)
= 6580 -240 - 7
= 6340 - 7
= 6333
L= 3w
Perimeter form = 2(l+w)
2(3w + w) = 112
6w + 2w = 112
8w = 112
w= 14
The greatest possible value for w is 14
Hope this helps!
