Question

The area of a square carpet is(36x²-12x+1) sq.meter.
a. Express the perimeter of the carpet in terms of x
b. If x= ½,find the perimeter of the carpet.
solve step by step
​

Answer 1

Answer:

4

Step-by-step explanation:

find factors of 36x²-12x+1

so,

36x²-12x+1 = 0

36x²-6x-6x+1 = 0

6x(6x-1)-1(6x-1) = 0

(6x-1)(6x-1) = 0

now the values of x will be.

x = 1/6, x = 1/6

so the area is

36(1/6)²-12(1/6)+1 = 0

1-2+1 = 0

a. 0

b. if x = 1/2

36(1/2)²-12(1/2)+1 = 0

9-6+1 = 0
