<h3>What is a rational number?</h3>
A rational number is a number that does not end in a non terminating decimal. Surd forms as well as the value pi are all irrational numbers. We must note that the option that has no surd form or pi as a denominator is a rational number.
Hence; the value written as 2/7 is a rational number and the other options are irrational numbers.

Answer:
Perimeter of the smaller square = 9 ft
Perimeter of the larger square = 18 ft
Step-by-step explanation:
Let
Perimeter of the smaller square = x
The perimeter of the larger square is twice the perimeter of the smaller square.
Perimeter of the larger square = 2x
Total Length of the piece of wire = 27 ft
Total = smaller + larger
27 = x + 2x
27 = 3x
x = 27/3
x = 9 ft
Perimeter of the smaller square = x
= 9 ft
Perimeter of the larger square = 2x
= 2(9)
= 18 ft
W = 135-98 =37
First you substitue the 98 to the left side then since it changes to negative in the rule of substition you can easily subtract and get the answer
Answer:
k > 100
Step-by-step explanation:
y= x²+20x+k
if the graph doesn't intersect the x-axis it means it has no real roots so the discriminat has to be negative so will have imaginary roots
discriminant is
b²-4ac = 20²-4*1*k = 400-4k for this to be negative k has to be more then 100 so will have 400 - a number bigger then 400
k > 100 is the solution
