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

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

i need the table so i can see
