Solve for the variable: -(3x)^2 + 3 = -6
Veronika [31]

Hey there! :)


-(3x)² + 3 = -6


Simplify.


-(9x²) + 3 = -6


Simplify.


-9x² + 3 = -6


Subtract 3 from both sides.


-9x² = -6 - 3


Simplify.


-9x² = -9


Divide -9 from both sides.


-9x² ÷ -9 = -9 ÷ -9


Simplify.


x² = 1


So, x = 1 OR x = -1


~Hope I helped!~

Rosa Roberto Andera and Inno find a estimate for ✓10. Who has proposed the best soulution?
emmainna [20.7K]

Answer:

D. Inno

Step-by-step explanation:

You can estimate cube roots by trying to get the two closest cube roots. Inno used √9 and √16. These two roots are the closest to √10. The cube root of √9 and √16 are 3 and 4 respectively, which means the √10 is between these two numbers, because √10 is between √9 and √16. √9 is the closest to √10, so the cube root of 10 is a number close to 3.

My english can be confusing but I tried :) Hope you understand it.
