blagie [28]
The total of the sweater is $27. 
Divide 18/1 by 2/3. You would get 27. Which means 1/3 of the sweater is $9. 
And 2/3 would be $18.

Find the two square roots of 144.
spin [16.1K]

Answer:

The square root function

sqrt(144) or √144 produces a single positive value, 12.  

However if you have an equation

x² = 144, then you have two possible values for x, 12 and -12.  

Two ways to look at it.  

x² - 144 = 0

Difference of two squares

(x+12)(x-12) = 0

x = -12, 12

x² = 144

x = ±√144

x = ±12

x = -12, 12
