Answer: A.  .
 .
Step-by-step explanation:
- A difference of squares problem is factored as : 
- For this both terms in the form of squares and a minus sign between them.
From all the options only option A has both terms square and they minus sign between them.
Also, 
Here a= 3x and b= 4
Hence, the correct answer is A.  .

- Length (l) = 45 m
- Breadth (b) = 30 m
- We know, perimeter of a rectangle = 2(length + breadth)
- Therefore, perimeter of the rectangle 
- = 2(I + b) 
- = 2(45 + 30) m 
- = 2 × 75 m 
- = 150 m
- So, the distance travelled by Rubina 
- = 4 × 150 m
- = 600 m
<u>Answer:</u>
<em><u>The </u></em><em><u>distance </u></em><em><u>travelled</u></em><em><u> </u></em><em><u>by </u></em><em><u>Rubina </u></em><em><u>is </u></em><em><u>6</u></em><em><u>0</u></em><em><u>0</u></em><em><u> </u></em><em><u>m.</u></em>
Hope you could get an idea from here.

-2/3x+9=4/3x-3 original problem add 2/3x to both sides
9=6/3x-3 simplify 6/3 to 2 and add 3 to both sides
12=2x  divide both sides by 2
x=6
hope that helps
 
        
             
        
        
        
Answer:
x = -y
or
-y = x
Step-by-step explanation:
since you reflect it over the x axis, the y changes to a negative
