Answer:
A. x > -3
Step-by-step explanation:
Well by looking at the graph we can tell that,
the line we can tell that the line goes to the right of of the number line,
Meaning x is greater than -3.
<em>Thus,</em>
<em>x > -3.</em>

-----------------------------------------------
Define x :
-----------------------------------------------
Let the width be x
Width = x
Length = 4x + 7
-----------------------------------------------
Formula :
-----------------------------------------------
Perimeter = 2 (Length + Width)
Perimeter = 74
2(4x + 7 + x) = 74 // sub length and width into the equation
2(5x + 7) = 74 // combine like terms
10x + 14 = 74 // Apply distributive property
10x = 60 // Take away 14 from both sides
x = 6 // Divide by 10 on both sides
-----------------------------------------------
Find Length and Width :
-----------------------------------------------
Width = x = 6mm
Length = 4x + 7 = 4(6) + 7 = 31mm
----------------------------------------------------------------------------------------------
Answer: The length is 31mm and its width 6mm.

Answer:
Step-by-step explanation:
We have to simplify this equation.
<u>Like this:</u>
<u>The closest number to x is 19:</u>
<u>Solve:</u>
- 2 * 19 + 8 = 46
- = 38 + 8 = 46
- = 46.
x = 19.
X² -25 = 0
We can use formula a² -b² =(a-b)(a+b)
x² - 5² =0
(x-5)(x+5)=0
x+5 =0 or x-5 = 0
x=-5 or x=5
Answer is x=-5, x=5
Irrational
the number is endless in its digits (much like pi) and thus is irrational
