Expand and simplify: (x + 1) (x + 4) (x + 3) ! due in on friday and i have 9 other questions as well as this one! i wasn't in on the day we did this in lesson at school, so someone give me a right ? -will give 10 points to the winner xx

Multiple (x+1) (x+4) (x+3)

(x+1) (x+4)   FOIL

x² + 5x + 4  

(x² + 5x + 4 ) (x + 3) multiple it by x and then 3

x(x² + 5x + 4 )  =  x³ + 5x² + 4x

3(x² + 5x + 4 ) =         3x²   + 15x   + 12

now add them     x³ + 8x² + 15x + 12

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
