Xavier climbs 9 feet up into an apple tree. What integer represents the direction and how far he will climb to get back down to the ground? What does the integer 0 represent in this situation? The integer represents Xavier’s climb down. The integer 0 represents .

The answer is "-9 feet and Ground-level".

Step-by-step explanation:

Given value:

total length or distance from apple tree = 9 feets

In the calculation of the distance between both the ground and the tree will be the same.  

If he gets higher 9 feet, he will go back to the ground 9 feet, in this case, the represents ground  value is equal to 0.

In the calculation of absolute values it value is opposite but the same.

0,0

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
