Choose one of the factors of x3 − 1331.

x − 11
x2 − 11x + 121
x2 + 22x + 121
none of the above

The correct option is:  

Step-by-step explanation:

The given expression is:  

If we factor out 1331, then we will get: which is

So, the expression becomes:  

Now, the formula we need to apply here:  

Applying the above formula......

So, one of the factors is  

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
