The square of a rational number is a rational number.
<h3>What are rational numbers?</h3>
A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero.
A rational number is a number that is of the form p/q where p and q are integers and q is not equal to 0.
Therefore, rational numbers are express as follows; p / q.
Hence, x is a rational number . let's confirm that x² is rational or not.
Therefore, When we square a rational number, each prime factor has an even exponent.
For example
p / q = p²/ q²
Hence, the square is a rational number.

Answer:
A
Step-by-step explanation:
covert to slope intercept form
x-y=2
-y=-x+2
y=x-2
Answer:
( 8 , 6 )
Step-by-step explanation:
A = ( 2 , 2 ) and C = ( 5 , 4 )
→ Form an equation
and 
→ Now solve them
2 + x = 10 and 2 + y = 6
→ Simply find the values
x = 8 and y = 6
(7+2-3-8)=0
