The equation that describes the which gives the area of the pen, A, as a function of x, the length of fence parallel to the barn is A = 130x - x²
<h3>How to find area of a rectangle?</h3>
The pen is rectangular. Therefore,
area of a rectangle = lw
where
Therefore,
perimeter = 2w + l
perimeter = 2w + x
130 = 2w + x
130 - x = 2w
w = 65 - 1/ 2 x
A = xw
A = x(65 - 1/ 2 x)
A = 65x - 1 / 2 x²
Therefore, the function that represents A, the area of the pen is as follows:
A = 130x - x²

Answer:
Step-by-step explanation: I believe you would just take 147 + 224 + 175 + 273 = 819pi cm2
So your answer would be 819pi cm2
Answer:
b
Step-by-step explanation:
yeah its just b since you just need to circle the answer. I hope it helped!
4 / (1/4 - 5/2)
4 / (1/4 -10/4)
4 / (-9/4)
4 x (-4/9) = -16/9
The sum of 6 and x is less than or equal to - 20.
Answer: (6+x) ≤ -20
