can you give me brainlist


let x=width, so 2x=length

area = area __ (x+3)(2x+3) = (x)(2x) + 54

2x^2+9x+9 = 2x^2+54

subtracting 2x^2+9 __ 9x = 45

dividing by 9 __ x = 5

What is the equation of this line?<br><br> y=34x−3<br><br> y=−3x−34<br><br> y=−3x−43<br><br> y=43x−3
zhuklara [117]

Step-by-step explanation:

this line goes through the points (0, -3) and (4, 0).

so, the y-axis intercept is at y = -3.

therefore, the equation has to end with "- 3".

the slope (the factor of x in the equation) is the y/x ratio of the changes of y and of x when going from one point to the other :

x changes by 4 positive units (from 0 to 4), and y changes by 3 positive units (from -3 to 0).

so, the slope is 3/4.

and so, the equation is

y = (3/4)x - 3
