The area is given by
A = (5 + 2x) * (10 + 2x) - 50
Rewriting we have:
A = 50 + 10x + 20x + 4x ^ 2 -50
Rewriting we have:
A = 4x ^ 2 + 30x
Substituting the value of the area we have:
54 = 4x ^ 2 + 30x
Rewriting:
4x ^ 2 + 30x - 54 = 0
We look for the roots:
x1 = -9
x2 = 3/2
We take the positive root:
x2 = 3/2
Answer:
the value of x is:
x = 3/2

Answer:
Least common denominator is 6x^2
Step-by-step explanation:

Here we have denominators x and 6x^2
we take the factors for x and 6x^2
x ---> x
6x^2 ----> 3 * 2* x*x
WE have x in common
To get LCD we multiply all the numbers but repeated x only once
LCD is 3*2*x*x that is 6x^2
Least common denominator is 6x^2
