24 POINTSSS for anyone who answers The of a square garden is 36x^2 -60+25 find the perimeter if x=3
Misha Larkins [42]

Answer:

The perimeter is 52

Step-by-step explanation:

The area is 36x^2 -60x+25

We set this equal to 0 to find the length and width

A= 36x^2 -60x+25

We notice that this is a perfect square trinomial

(a^2 -2ab-b^2) = (a-b)^2

let a = 6x  and b=5

A=(6x-5) (6x-5)

The length and width are the same since is it a square  (we know it is a square so they have to be equal)

The perimeter of a square is

P =4s

P =4 (6x-5)

Distribute the 4

  = 24x -20

Let x =3

P = 24(3) -20

  =72 -20

 = 52

The perimeter is 52

Evaluate the polynomial for the given value of x: f(x) =3x^3+5x^2+x-2 when x=2
sasho [114]

Answer: f(2)=44

Step-by-step explanation:

Given the polynomial f(x) =3x^3+5x^2+x-2, you can evaluate it for the given value of the variable "x" by substituting the value x=2 into the polynomial.

Therefore, when x=2,  you get the following result:

f(x) =3x^3+5x^2+x-2 \\\\f(2) =3(2)^3+5(2)^2+(2)-2\\\\f(2)=3(8)+5(4)+2-2\\\\f(2)=24+20\\\\f(2)=44
