40 4/5 is the answer i believe. Just message me if you need help okay sweetie? :)
Answer:
value of x is 13.5 inches.
<em>hope </em><em>this </em><em>answer </em><em>helps </em><em>you </em><em>dear.</em><em>.</em><em>.</em><em>.</em><em>take </em><em>care!</em>
<em>perimeter</em><em> </em><em>=</em><em> </em><em>2</em><em>l</em><em> </em><em>+</em><em> </em><em>2</em><em>b</em><em> </em><em>too </em><em>and </em><em>it </em><em>is </em><em>also </em>
<em>2</em><em> </em><em>(</em><em> </em><em>l </em><em>+</em><em> </em><em>b </em><em>)</em>
<em>→</em><em> </em><em>2</em><em>l</em><em> </em><em>+</em><em> </em><em>2</em><em>b</em>
<em>breadth</em><em> </em><em>and </em><em>width</em><em> </em><em>are </em><em>same!</em>
The answer is: " x = 0, 1 " .

Explanation:
__________________________________________
Given:
__________________________________________
" √(x + 1) <span>− 1 = x " ; Solve for "x" ;
First, let us assume that "x </span>≥ -1 "
<span>
Add "1" to EACH SIDE of the equation:
</span>→ √(x + 1) − 1 + 1 = x + 1 ;
to get:
→ √(x + 1) = x + 1 .
Now, "square" EACH side of the equation:
→ [√(x + 1) ]² = (x + 1 )² ;
to get:
x + 1 = (x + 1)²
↔ (x + 1)² = (x + 1) .
Expand the "left-hand side" of the equation:
→ (x + 1)² = (x + 1)(x +1) ;
Note: (a+b)(c+d) = ac +ad + bc + bd ;
As such: (x + 1)(x + 1) = (x*x) + (x*1) +(1(x) + (1*1) ;
= x² + 1x + 1x + 1 ;
= x² + 2x + 1 ;
Now, substitute this "expanded" value, and bring down the "right-hand side" of the equation; and rewrite the equation:
__________________________________________
" (x + 1)² = (x + 1)(x +1) " ;
→ Rewrite as: " x² + 2x + 1 = x + 1 " ;
Subtract "x" ; and subtract "1" ; from EACH SIDE of the equation:
→ x² + 2x + 1 - x - 1 = x + 1 - x - 1 ;
to get: → x² <span>− x = 0
Factor out an "x" on the "left-hand side" of the equation:
___________________________________________
</span>x² − x = x(x − 1) ;
→ x (x − 1) = 0 ;
We have: "x" and "(x − 1)" ; when either of these two multiplicands are equal to zero, then the "right-hand side of the equation equals "zero" .
So, one value of "x" is "0" .
The other value for "x" ;
→ x − 1 = 0 ;
Add "1" to each side of the equation:
→ x − 1 + 1 = 0 + 1 ;
→ x = 1 ;

So, the answers:
" x = 0, 1 " .

Nonlinear has a break or is noncontinuous
For example x is not equal to 4
