A) 3
B) -1
C) 0
Step-by-step explanation:
You can use Desmos graphing calculator and input the equations. I hope this helps and please mark Brainliest!
X² = 17
To simplify this, you need to find the square root of x², which is x, and the square root of 17.
x = √17
Also remember that when you are using square root, the answer can be either positive or negative.
x = +/-√17 ≈ +/- 4.12
Remark
The best way would be to make a duplicate of this page and cut out the shapes. Then find out which ones fold into a cube. It would also be the most time consuming.
The second best way is to imagine how each flat surface would fold to make a cube. I think C would and D would. I don't think the other 2 would.
The answer is b because the square root of 7 is 2.6.
