Answer:
The area is rational because the numbers in the formula are rational.
Step-by-step explanation:
All repeating decimals are still rational because they can be expressed as fractions. For example,
So every recurring decimal must be a fraction.
Also every terminating decimal can be represented as a fraction.
0.25 = 
So the area is rational because the numbers are rational.
Area = 
X Base X Height
Base is Rational and Height is Rational. Hence Area=Rational.
When these rational numbers are substituted into the formula,the area must be rational.
Answer:
The answer is A
Step-by-step explanation:
When two parallel lines are crossed by another line the angle of 1 will be equal to 4, 5, and 8. The angle 2 will be equal to 3, 6, and 7. Since a straight line has a degree of 180, the subtracted degree of 180-140=40 which would mean 2=40 which 2=6 so 6=40.
sub 2 for any "x"
3(2)^2-2(2)+1
6^2-4+1 i dont know if you need to simplify even more but if you do
36-4+1 32+1 31
i hope this helps you!
Answer:
combining 2x and 4x to make 6x
Step-by-step explanation:
Answer:
Step-by-step explanation:
we have
-----> equation A
----> equation B
To find the solutions for x of the system of equations
equate equation A and equation B
The values of x of the intersection points are the solutions of the system
Using a graphing tool
see the attached figure
There are two intersection points
therefore
The solutions are
