So here is how you solve for the answer.
Firstly, you solve for the Area of Rectangle A.
The formula for Area is Length x width.
So A = (2x + 6)(3x) and the result is: 6x^2 + 18x
Now, let y be the width of rectangle B.
<span>(x+2) (y) = 6x^2 + 18x + 12
(x+2) y = 6(x+1)(x+2)
y = 6(x+1)
</span>So the final answer would be width is 6x + 6. The answer is the third option. Hope this answer helps.

Follow the PEMDAS order of operation:
- P = Parenthesis
- E = Exponents
- M = Multiplication
- D = Division
- A = Addition
- S = Subtraction
<em>You do these steps in the order for which the equation comes. For example, start with the exponents if there are not any parentheses.</em>
Step-by-step explanation:
We have,
The wavelength of yellow light, 
Frequency of yellow light, 
It is assumed to find the speed of light in the yellow light.
The speed of a wave is given in terms of wavelength and frequency as :

So, the speed of light in a shade of yellow light is
.
<span>We have the function: f ( x ) = ( x + 6 ) ( x + 6 ) = ( x + 6 )^2. This is the square of the binomial. It has only one zero ( only one x- intercept ). When f ( x ) = 0, ( x + 6 )^2 = 0. x + 6 = 0; x = - 6. Therefore point ( - 6 , 0 ) is the only x - intercept. Answer: D ) f ( x ) = ( x + 6 ) ( x + 6 ).</span>
