Answer:
193
Step-by-step explanation:
Let's "cheat" a little on this one
We know that the numbers are consecutive
so lets take the square root of 9312 to get close
√9312 = 96.4987046545
Consecutive numbers around 96.4987046545
96 * 97 = 9312
96 + 97 = 193
-------------------------------
The "correct" method would be to set up an equation
x(x + 1) = 9312
x² + x = 9312
x² + x - 9312 = 0
Then use the quadratic equation to solve for x
Which you can do if you're so inclined.
Me, I'm happy to have "cheated"
Answer:
168 cm³
Step-by-step explanation:
The base area of the oblique hexagonal prism = 42 cm²
the height of the prism = 4 cm
Volume of the prism = Base area × height = 42 cm² × 4 cm = 168 cm³

Step-by-step explanation:
1
Given
2x² - 16 = 0 ( add 16 to both sides )
2x² = 16 ( divide both sides by 2 )
x² = 8 ( take the square root of both sides )
x = ± 
= ± 2
------------------------------------
2
Given
- 5x² + 9 = 0 ( subtract 9 from both sides )
- 5x² = - 9 ( divide both sides by - 5 )
x² = 
( take the square root of both sides )
x = ± 
= ± 
-----------------------------------------
3
Given
6x² - 15 = 27 ( add 15 to both sides )
6x² = 42 ( divide both sides by 6 )
x² = 7 ( take the square root of both sides )
x = ±
