The answer is 73.33333333 (repeated). You can also write it as 73 or 73.3 with a line over the 3 (after the decimal point) to indicate it being repeated.
So b/10 has to be -1, that means b is -10
Answer:
second, third,first
Step-by-step explanation:
first
3/2=1.5
9^1.5=27
second
1/3=0.333
27^0.333=3
third
2/3=0.667
125^0.667=25
Answer:3 boxes.
Explanation: $21 / $7=3 boxes
Answer:
x^2 + 8x + 16
Step-by-step explanation:
Given length of square x + 4.
Area of square with side S is given by
.
Therefore are of square with side x + 4 is given by ![(x + 4)^2](https://tex.z-dn.net/?f=%28x%20%2B%204%29%5E2)
Area of square = ![(x + 4)^2\\=>(x + 4)*(x + 4)\\=> x(x + 4) + 4(x + 4)\\=> x^2 + 4x + 4x + 4*4\\=> x^2 + 8x + 16](https://tex.z-dn.net/?f=%28x%20%2B%204%29%5E2%5C%5C%3D%3E%28x%20%2B%204%29%2A%28x%20%2B%204%29%5C%5C%3D%3E%20x%28x%20%2B%204%29%20%2B%204%28x%20%2B%204%29%5C%5C%3D%3E%20x%5E2%20%2B%204x%20%2B%204x%20%2B%204%2A4%5C%5C%3D%3E%20%20x%5E2%20%2B%208x%20%2B%2016)
Thus, x2 + 8x + 16 expression represents the area of a fabric square.
