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.

The width of a rectangle is the sum of the length and 1. The area of the rectangle is 20 units. What is the width, in units, of
IRISSAK [1]

Answer:

W=5

Step-by-step explanation:

W=Width=Length + 1

L = Length

Area = Length * Width = 20

Area = L * W = L * (L+1) = 20

Distribute the L:   L^2 + L = 20

Subtract 20 from both sides: L^2 + L -20 = 20-20

Simplify:  L^2+L-20=0

Factor (L-4)(L+5)=0

Solve using the zero property: L-4=0, L=4      L+5=0, L=-5

The two options for length are 4 and -5. Only 4 will work for L since it cannot be negative.   Width is Length + 1 = 5

"With patience a ruler may be persuaded, and a soft tongue can
Maru [420]

Answer:

Well rulers don't like to be proven wrong therefore you have to be patient in convincing a ruler that your idea is best. It's pretty much like what inception is in the movie.

A soft tongue is using calm words which in my opinion means you have the utmost confidence in what you're saying. I dont think it literally means bones will break but the person listening will feel as though they are completely wrong if a calm cool person is proving them wrong.
