Answer:
√135
Step-by-step explanation:
3^2+b^2=12^2
9+b^2=144
9-9+b^2=144-9
b^2=135

Are you looking for the value of x?
We can complete the square/factor:
x^2+7x-30=0
(x+10)(x-3)=0
By the zero product property rule, we have two equations, x+10=0 and x-3=0.
So the zeroes of x are -10 and 3
Hope this helped. Comment below if this didn't make sense.
 
        
             
        
        
        
Answer:
22.74 liters
Step-by-step explanation:
GIven data
Felix's washing machine uses 6 gallons of water
we are told that  A gallon is approximately 3.79 liters
Hence if  a gallon is approximately 3.79 liters
then 6 gallons of water will be x liters
cross multiply we have
x= 6*3.79
x= 22.74 liters
Hence 6 gallon will be 22.74 liters
