Answer: 226.5 ft²
<u>Step-by-step explanation:</u>
I divided the image into 3 rectangles and 1 triangle.
top rectangle: length = 9, height = 4 --> A = 9 x 4 = 36
middle rectangle: length = 15, height = 7 --> A = 15 x 7 = 105
bottom rectangle: length = 18, height = 4 --> A = 18 x 4 = 72
triangle: base = 9, height = 3 --> A = (9 x 3)/2 = <u> 13.5 </u>
<u>Total </u> = 226.5
Me not knowing what any of that is

Step-by-step explanation:
<u>Step 1: Define</u>
-12(x + 4) + 14x = 60
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -12: -12x - 48 + 14x = 60
- Combine like terms: 2x - 48 = 60
- Add 48 to both sides: 2x = 108
- Divide 2 on both sides: x = 54
Answer:
Step-by-step explanation:
The square root of a perfect square is a rational number.
So let us take the square root of each number to see which is a rational number.
......irrational
......rational
.........irrational
