If you would like to know how many gallons of paint did Beth use, you can calculate this using the following steps:
1 jar ... 1 pint of paint
32 jars ... x pints of paint = ?
1 * x = 1 * 32
x = 32 pints of paint
1 gallon ... 8 pints
y gallons = ? ... 32 pints of paint
1 * 32 = 8 * y
32 = 8 * y /8
y = 32 / 8 = 4 gallons of paint
Result: Beth used 4 gallons of paint.
Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.
