Alex wants to fence in a rectangular pasture that has a length of 54 m and a width of 90 m. he wants to place all the fence posts an equal distance from one another. he puts in each of the four corners and places each post as far as possible from the next. what is the distance between the posts? how many posts does he need?

Hi there i'm going to do everything in my power to help you for this question of yours.

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
