I think the answer is 1
Explanation:2x+2=x+3
Subtract the 2 and the x from both sides
1x=1
Divide by one then you get 1

Answer:
He started with 180.
Step-by-step explanation:
If 90 is 50% of what he started with, then the other 50% is 90
Answer:
h=3.9x+15.85 meters
Step-by-step explanation:
Let's say that the height of the floor just before the roof to the highest point of the roof is also 3.9 m, perhaps, we have an almost flat roof
Since the FM radio antenna is fixed on top of roof, the total height is that of previous floors and the antenna
Taking the building to have x number of floors with each floor having 3.9 m height, the function of height will be
h=3.9x + 15.85 meters
The number added to the polynomial by completing the square is ![\frac{289}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B289%7D%7B4%7D)
Explanation:
Given that the polynomial is ![x^{2} +17x](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B17x)
We need to determine the number that is added to the polynomial to complete the square.
The last term of the polynomial can be determined by dividing the term 17 by 2 and then squaring the term.
Thus, we have,
Last term = ![\frac{17}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B2%7D)
Now, squaring the term, we have,
Last term = ![(\frac{17}{2})^2=\frac{289}{4}](https://tex.z-dn.net/?f=%28%5Cfrac%7B17%7D%7B2%7D%29%5E2%3D%5Cfrac%7B289%7D%7B4%7D)
Thus, the number added to the polynomial by completing the square is ![\frac{289}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B289%7D%7B4%7D)
