The answer is D
0 is not less than or equal to -4, and in the second equation, 0 is greater than -1
 
        
                    
             
        
        
        
Answer:  x = 7
`Step-by-step explanation:
Because the figure shows two triangles that are similar. we can write and solve an equation of ratios:
  9 cm       72 cm
----------- = -----------
 3x - 20      56 cm
Cross-multiplying, we get (3x - 20)(72 cm) = (9 cm)(56 cm) = 504 cm²
Dividing both sides by 72 cm, we get:
3x - 20 = (504 cm²) / (72 cm) = 7
Then 3x - 20 = 7, and 3x = 27.  Then x must be 9.
 
        
                    
             
        
        
        
Answer: 5.150
Step-by-step explanation:
1. Multiply 28 by 6/7
2. Multiply 21 by 2/9
3. Divide 24 by 4.66
 
        
             
        
        
        
A = L * W
A = 70
70 = L * W
P = 2(L + W)
P = 34
34 = 2(L + W)
34/2 = L + W
17 = L + W
17 - W = L
70 = L * W
L = 17 - W
70 = W(17 - W)
70 = -W^2 + 17W
W^2 - 17W + 70 = 0
(W - 10)(W - 7) = 0
W - 10 = 0        L = 17 - 10
W = 10              L = 7
W - 7 = 0          L = 17 - 7
W = 7               L = 10
so either the width is 10 meters and the length is 7 meters OR the width is 7 meters and the length is 10 meters
        
             
        
        
        
Answer:
Option A
Step-by-step explanation:
22+(-32) is the same thing as 22-32.

<h3>Let's see if the given options are equal:</h3>
Option A:

Option A's expression has the same value as the expression given. 
Option B: 
22+(22)+(-10)

Option B's expression does not have the same value as the expression given. 
Option C:

Option C's expression does not have the same value as the expression given. 
Option D: 

Option D's expression does not have the same value as the expression given. 
<h3>The correct answer should be A: 22+(-22)+(-10).</h3>
