Answer:
1/3x - 1/3
Step-by-step explanation:
First off, we can write this the words as a mathematical equations so its easier to work with:
1/3 (x - 1)
Now we can use distributive property and finally simplify this equation:
1/3 (x-1)
1/3x - 1/3 x 1
1/3x - 1/3
Answer:
30
Step-by-step explanation:
since the width is 20, there are 2 sides, so multiply by 2 and it's 40. Subtract 40 from 100 and you get 60. 60 is both lengths combined, so divide by 2 and you have 30 as your length. :)
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
divide the base by the sin of the opposite angle
base = 2
opposite angle = 30 degrees
2/sin(30) = 4
x = 4
