Answer:
21^2 − 14 − 7
Step-by-step explanation:
(3+1)(2+5−7)
(3x+1)({\color{#c92786}{2x}}+{\color{#c92786}{5x}}-7)
(3x+1)(2x+5x−7)
(3+1)(7−7)
(3x+1)({\color{#c92786}{7x}}-7)
(3x+1)(7x−7)

So let's convert these to improper fractions:
Then let's convert these fractions so that they have a denominator of 15 so we can better compare these numbers:
So when we have 
gallons splash out, we are left with 
gallons or 
gallons in the tub.
Answer:
it is 4
Step-by-step explanation:
i will do this some other time
Use the Pythagorean Theorem:
a^2 + b^2= c^2
a= one side= 68 mi
b= second side= 80 mi
c= hypotenuse= Greenville to Columbia mi
a^2 + b^2= c^2
68^2 + 80^2= c^2
square each number
4,624 + 6,400= c^2
11,024= c^2
take square root of both sides
104.995 mi= c
ANSWER: The distance from Greenville to Columbia is 104.995 miles (rounded to 105 miles).
Hope this helps! :)
