Here is another riddle: The sum of two numbers is less than 2. If we subtract the second number from the first, the difference is greater than 1. What are the two numbers? The riddle can be represented by a system of inequalities. Write an inequality for each statement.

Let x, y be the two numbers under consideration. Then, x+y<2 and x-y>1.

x=0

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
