lance bought a square postage stamp to a mail a card to his cousin. if the stamp has 4 square centimeters.what was the dimension
Lubov Fominskaja [6]

The dimension of one side of the stamp was 2 centimeters

Step-by-step explanation:

The formula of the area of any square is A = l², where l is the

length of the side of the square

lance bought a square postage stamp to a mail a card to his cousin

∵ The stamp has 4 square centimeters

∴ The area of the stamp = 4 cm²

∵ The stamp shaped a square

∵ The formula of the area of the square is A = l²

- Equate the formula of the area of the square by the area of the stamp

∴ l² = 4

- Take √ for both sides to find l

∴ l=\sqrt{4}

∴ l = 2 cm

The dimension of one side of the stamp was 2 centimeters

What values of x make the equation x2 + 9x – 22 = 0 true? Check all that apply. –11 –2 0 2 11
Marat540 [252]
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 .

How do you solve -5m+9n= 15, for m
Fed [463]

Answer:

m= 9/5 n - 3

Step-by-step explanation:

Let's solve for m.

−5m+9n=15

Step 1: Add -9n to both sides.

−5m+9n+−9n=15+−9n

−5m=−9n+15

Step 2: Divide both sides by -5.

-5m/-5 = -9n+15/-5

m= 9/5 n - 3

How do I solve the for x. 6x + 3 &gt; 21
Iteru [2.4K]

Answer:

x > 3

6x + 3 > 21 (Move the constant, +3 to the right hand side and change its sign)

6x > 21 -3 (Subtract 21-3)

6x >18 (Divide both sides by 6)

x > 3
