Given:

The equation is

9x^2-12x+4=49

To find:

The equation after first step to solve the given equation by using square root property.

Solution:

We have,

9x^2-12x+4=49

It can be written as

(3x)^2-2(3x)(2)+(2)^2=49

(3x-2)^2=49            [\because (a-b)^2=a^2-2ab+b^2]

Therefore, the equation can be rewritten in first step as (3x-2)^2=49.

A square piece of paper has an area of 36 square inches what is the perimeter of the paper​
Gekata [30.6K]

Lets represent the side of the square as s , since we know the area is 36. write s

{s}^{2}  = 36

s = \sqrt{36}

the square root of 36 is 6. So, we know the side is 6. The formula for perimeter is P= s+s+s+s , but since it is a square and all the sides are equal, for a perimeter of a square you can do p= 4s , now substitute 6 for s to get 4(6)=24 so the perimeter of a square would be 24 inches
