Sianna bought 3 pens, 4 notebooks, and a calculator. the calculator cost $25. if x represents the cost of each pen and y represents the cost of each notebook, which expression represents the amount of change sianna should receive from $50?
*3x + 4y +25
*50 – (3x + 4y)
*50 – (3x + 4y + 25)
*3x + 4y + 25 + 50

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

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
