Answer:
Step-by-step explanation:
x^2-6x=7 is our equation
x^2-2*3*x= 7
So the term we will be adding is 3^2 since 3 the second term is 2*3*x
x^2-6x+9=7-9
We added 9 and substract it to keep the equation
(x+3)^2 = -2
Wich is impossible since a squared number is always positive
Answer:
6

6×216=1296
6×1296=7776
6×n=...............
Answer:
rate = 316800 feet miles per hour
unit = feet per hour
Step-by-step explanation:
swimming rate of fish = 60 miles per hour
1 mile = 5280 feet
60 miles = 60*5280 feet = 316800 feet
swimming rate of fish = 60 miles per hour
substituting 60 miles with with its equivalent in feet we have
swimming rate of fish = 316800 feet miles per hour
answer
rate = 316800 feet miles per hour
unit = feet per hour
