Daria was trying to get to her parents house. For 50 miles she was stuck in traffic. For the remaining 100 miles she was able to travel twice as fast.

Find an expression to represent the amount of time it took Daria to get to her parent's house.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

4+4+2x

or

2x+8

step-by-step explanation:

2y+y=5

add 2y and y
