Well for 11, it is an inequality, a > sign or < sign with a little underscore mean either "greater than or equal to" or "less then or equal to" so 30> 12+m (>with an underscore) means 30 is greater than or equal to 12+m

Solve the equation : x^(2)+5=3(x^(2)-3)
Fittoniya [83]

Answer:

x = ± 2

Step-by-step explanation:

Given

x² + 5 = 3x² - 3 ( subtract x² + 5 from both sides )

0 = 2x² - 8 ( add 8 to both sides )

8 = 2x² ( divide both sides by 2 )

4 = x² ( take the square root of both sides )

x = ± \sqrt{4} = ± 2
