Answer:
x<4
Step-by-step explanation:
3x < 12
Divide with 3 on each side
x< 4
In words x has all the real numbers that are less than 4 or x belongs to any number from -ve infinity to 4.
Answer: x = 2 ; -11 .

Explanation:
_____________________________________________
Given the equation:
_____________________________________________
x² + 9x −<span> 22 = 0 ; Solve for: "x" ;
_____________________________________________
Let us factor the "left-hand side" of the equation:
_____________________________________________
"x</span>² + 9x −<span> 22" ;
_____________________________________________
What are the factors of "-22"" that add up to "positive 9" ?
_____________________________________________
Let us list the factors of "-22" :
____________________________________________
-2, 11; </span>→ -2 + 11 = 9 ;<span>
-11, 2; </span>→ -11 + 2 = -9 ;<span>
____________________________________________
So we have: "-2" and "11" ;
____________________________________________
So; </span> "x² + 9x − 22" ; factors into " (x−2)(x + 11)" ;
____________________________________________
We have: (x−2)(x + 11) = 0 ;
So: x − 2 = 0 ;
Add "2" to each side of the equation;
x − 2 + 2 = 0 + 2 ;
x = 2 ;
___________________________________
x + 11 = 0 ;
Subtract "11" from each side of the equation;
x + 11 − 11 = 0 − 11 ;
x = -11 ;

Answer: x = 2 ; -11 .

Answer:
c = 9/16
Step-by-step explanation:
<h3>step1</h3>
(a-b)²
a² - 2ab + b²
here a = x
b = ?
so
x² - (2)(x)(?) + ?²
Now we can see that -(2x)? = -3x/2
-2x? = -3x/2
cancel -x on both sides
2? = 3/2
? = 3/2 * (2)
? = 3/4
so b = 3/4
<h3>step2</h3>
(x² - 3x + 9/16) = (x-3/4)²
so from the expression we can see that C = 9/16
We know that
in the triangle ABC
∡A+∡B+∡C=180°
∡C=180-(50+100)-------> ∡C=30°
triangle ABC and triangle XYZ are similar
so
∡X=∡A
∡Y=∡B
∡Z=∡C
hence
∡Z=30°
the answer is∡Z=30°
3 ×+8y=0
