B. -11f + 15

C. None of the above

C. None of the above

Step-by-step explanation:

Which expressions are equivalent to -f-5(2f-3)−f−5(2f−3) ?

A. -11f - 3

B. -11f + 15

C. None of the above

To find the  expressions that are equivalent to -f-5(2f-3)−f−5(2f−3), we will follow the steps below:

-f-5(2f-3)−f−5(2f−3)

lets start by opening the parentheses

-f -10f+ 15-f-10f + 15

add the like terms together

-f -10f-f-10f + 15+ 15

-22f + 30

The expression   -f-5(2f-3)−f−5(2f−3)  is equivalent to -22f + 30

Therefore non of the first to option is equivalent to the given expression, hence the correct option is c. none of the above

the correct answer is the second option

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
