3 + (-4) is the same thing as 3 - 4.
3 - 4 = -1
Hope this helped :)
Good morning.
In level
4, the experience needed is:
![\mathsf{g(4) = 7\cdot3^{4-1}}\\ \\ \mathsf{g(4) = 7\cdot3^3 = 7\cdot27}\\ \\ \mathsf{g(4) = 189}](https://tex.z-dn.net/?f=%5Cmathsf%7Bg%284%29%20%3D%207%5Ccdot3%5E%7B4-1%7D%7D%5C%5C%20%5C%5C%20%5Cmathsf%7Bg%284%29%20%3D%207%5Ccdot3%5E3%20%3D%207%5Ccdot27%7D%5C%5C%20%5C%5C%20%5Cmathsf%7Bg%284%29%20%3D%20189%7D)
In the hardest settings, the multiplier is:
![\mathsf{h(4) = 4\cdot 4}\\ \\ \mathsf{h(4) = 16}](https://tex.z-dn.net/?f=%5Cmathsf%7Bh%284%29%20%3D%204%5Ccdot%204%7D%5C%5C%20%5C%5C%20%5Cmathsf%7Bh%284%29%20%3D%2016%7D)
So, the adjusted experience points are:

“Three decimal places” is the same as “the nearest thousandth.” So, for example, if you are asked to round 3.264 to two decimal places it means the same as if your are asked to round 3.264 to the nearest hundredth. Some questions, like the example below, will ask you to “show your answer correct to two decimal places."
Answer:
![c\leq \$17](https://tex.z-dn.net/?f=c%5Cleq%20%5C%2417)
Step-by-step explanation:
Let
c -----> the additional amount (in dollars) David will spend
we know that
The word " at most" in this context means "less than or equal to"
The amount David has spent plus possible additional amounts he will spend must be less than or equal to $39
so
The inequality that represent this situation is
![22+c\leq 39](https://tex.z-dn.net/?f=22%2Bc%5Cleq%2039)
solve for c
subtract 22 both sides
![c\leq 39-22](https://tex.z-dn.net/?f=c%5Cleq%2039-22)
![c\leq \$17](https://tex.z-dn.net/?f=c%5Cleq%20%5C%2417)
The maximum amount he could spend is $17
Both missing angles are 45°
