System of equations:
w=(3/2)*h          (1)
w*h=54      area (2)

w=54/h substitute into (1)
54/h=3h/2
3h²=54*2
h²= 36  (we take only positive solution)
h = √36=6
h=6 in.
w=(3/2)*h=(3/2)*6= 9
w=9 in.
correct answer is D

Steps for solving 3x+18=54 are shown explain how step 1 helps solve the equation
Dennis_Churaev [7]

Answer:

The answer is x=12.

Step-by-step explanation:

First, to solve this equation you need to isolate the x variable. To isolate the variable, you must, subtract the other term from both sides. Subtracting 18 from both sides, you are left with 3x = 36. Since 3 times x = 36, dividing both sides by 3 gets you, x=12.
