Write the expression in factored form s^2-20s-100
KatRina [158]

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.

Ostrovityanka [42]

Answer:

The trucking company shipped a total of 151 thousands of boxes of fruits

Step-by-step explanation:

Total boxes of fruits shipped= 151,375

How many thousands of boxes of fruit were shipped?

To find the thousands of boxes of fruits shipped, divide the total number of boxes of fruits shipped by 1000

That is

151,375 / 1000

= 151.375

Therefore, the trucking company shipped a total of 151 thousands of boxes of fruits

151,375
