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:
12 rides
Step-by-step explanation:
First, get the total and subtract it from the expenses.
34 - 8.50 - 4.50 = 21
Then divide the answer by how much each ride costs to find the answer
21 ➗1.75 = 12
So Sam can ride 12 rides.
Answer:
I believe it would be 0.6 Because 1.8 is 1.2x1.5 so if you take 0.4x1.5 you get 0.6
