If the area A of the square is known, then the lengths of its sides (e) can be computed using (e)=. You have purchased a 169 share in a community garden for the season. What is the length of one side of your square garden?

1.677

step-by-step explanation:

i'm not good at explaining stuff but if you need an answer i'm here for you.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

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
