I have a feeling its c but i might be wrong...
We are given the following equation:
![a^2+17=42](https://tex.z-dn.net/?f=a%5E2%2B17%3D42)
Subtract both sides by 17
![a^2=25](https://tex.z-dn.net/?f=a%5E2%3D25)
Take the positive/negative square root of both sides
![a=\pm5](https://tex.z-dn.net/?f=a%3D%5Cpm5)
This should be your answer. Let me know if you have any questions, thanks!
Answer:
c
Step-by-step explanation:
4x-8q=-32q
4x-4=-16
10-16=-6
-32q-6
100% - 75 %= 25% ($48 is 25 percent of the original price)
finding original price = price after discount / percentage
= $48 ÷25%
=$48 × 100/25
=$48 × 4/1
=$192 (original price)
