1. Six less than n is less than - 4. how would o write this equation <br>​
posledela

Answer:

n - 6 < -4

Step-by-step explanation:

6 being less than n hints at a subtraction equation, n coming first as the value of the constant is currently unknown. 'Less than -4' hints that -4 is the value on the other side of the inequality, < acting as the 'equal' sign in this sense.

Problem #32 <br> I am not sure if I did this right can you check please and explain
Natasha2012 [34]

Answer:

Step-by-step explanation:

It seems you got the right answer, but didn’t do the problem correctly.

The square root of 2 times the square root of 2 is 2. And then 6 times the square root of two minus the product of 6 and the square root of two equals zero. And then obviously 6 and -6 equals -36. So 2+-36 is -34
