Simplify by factoring. assume that all expressions under radicals represent nonnegative numbers.

what is the simplified form of the expression?

x>0 and working with real numbers

OR

x<0 and working with imaginary/complex numbers

OR

Leave it like the following for both systems(Real/Complex) numbers

First simplify

Find a perfect square and a non perfect square, which when you multiply the two squares it gives you

Now get the square root of if we are working with real numbers and  x > 0

If x not > 0 then just leave as

Now combine it all

OR

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

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
