Let x = the width and x + 30 = the length.
x(x + 3) = 8800
x^2 + 3x = 8800
x^2 + 3x - 8800 = 0
Using the Quadratic Formula, I get x ≈ 92.320 yd and x + 30 ≈ 122.320 yd.
2x + 2x + 60 = 600
4x + 60 = 600
4x = 540
x = 135
x + 30 = 165
The area would be 22275 yd^2.
<u>Answer</u>
The simplified form of the expression is 11a.
<u>Explanation</u>
10a + a
a + a + a + a + a + a + a + a + a + a = 10a
10a plus one more a, equals 11a.
Hope I helped :)
The LCM is the smallest common multiple of two or more numbers. For example, the LCM of 2 and 5 is 10. The least common factor is the smallest common factor of two or more numbers. The smallest factor of every number is 1.

When 48 is factored, it factors to 4²×3. When you take the square root of that, you get 4√3.
It’s c
You would use cah which is cosine
20 x cos(30
