Answer:
Parallel: G and F
perpendicular: G & H, F & H
Step-by-step explanation:
G and F are parallel because they will never cross, where as both are perpendicular to H because they intersect at 90°
Answer: D.-6 and F.3
Step-by-step explanation:
The given rational number : 
To find : The value of x , where the rational expression becomes equal zero.
Let's check all the options :
A. 7
At x= 7 , 
B. -7
At x= 7 , 
C. 6
At x= 6 , 
D. -6
At x= -6 , 
E. -3
At x= -3 , 
F. 3
At x= 3 , 
Thus, at x= -6 and 3 , the rational expression equals to zero .
So , the correct options are : D.-6 and F.3
Answer:
48% of 25 is 12.
Step-by-step explanation:
To find : what percent of 25 is 12?
Solution : Let x be the percentage of 25 which is 12
So, by the statement
x% of 25 = 12
Now, we have to calculate the value of x
Step 1- Write the expression

Step 2- divide 25 by 100

Step 3- Cross multiply

Therefore, 48% of 25 is 12.
a^2 +b^2 = (2.5sqrt(2))^2
2a^2 = 6.25 *2
a^2 = 6.25
a = sqrt(6.25)
a = 2.5
length of each side = 2.5 units
