Answer:
I believe the answer you are looking for is C
Step-by-step explanation:
7/12*6/14
7*6=42
12*14=168
=42/168
=0.25 =1/4
Let the length of the playground be x, then the width is 6 + x.
Area = length * width = x * (6 + x) = 6x + x^2 = 216
Solving the quadratic equation x^2 + 6x - 216 = 0, we have x = 12 or -18
i.e length = 12 and width = 6 + 18 = 18
The answer is O f(x) =-35x+5
The answer is D. 63. You have to set up a proportion as shwon in the image.
