A park is enclosed with a fence that is 82 feet long. the length of the park is 24 feet. what is the width of the park

17 feet

Step-by-step explanation:

The perimeter would thus be 82, as the fence is enclosing the park, and perimeter formula is : 2 * length + 2* width, so 82 = 2*length + 2*width

So given the length is 24 feet, plug it into the perimeter formula assuming width = x, to get:

82 = 2*24 + 2x,

82 = 48 + 2x,

34 = 2x,

x = 17 feet, the answer

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
