It’s the second one for sure
Answer: 3 degrees F
Step-by-step explanation:
Answer
x =
1/√3 and
x =
-1/√3 or in decimals x = + 0.577350269 and
= - 0.577350269
Explanation
-3(3x)² + 3 = -6
-3×9x² + 3 = -6
-27x² = -6-3
-27x² = -9
x² =-9/(-27)
= 9/27
x = +√(9/27)
x = 3/√27
= 3/√9×3
= 3/3√3
= 1/√3
or in decimals x = 0.577350269
Also x = -√(9/27)
x = +√(9/27)
x = -3/√27
= -3/√9×3
= -3/3√3
= -1/√3
or in decimals x = -0.577350269
A power is how many times a number is multiplied by itself. So for 3, the number given, the values are as follows:
3x3=9
3x3x3=27
3x3x3x3=81
3x3x3x3x3=243
3x3x3x3x3x3=729
The next power will be greater than 1000 and therefore out of the range given.
