Can someone me factor this?
a)
b)
c)
d)
!

(a+b)^2=a^2+2ab+b^2

(a-b)^2=a^2-2ab+b^2

x^2-4x+4=x^2- 2*2*x +2^2=(x-2)^2

The answer is B

You can check like this:

(x-2)^2=(x-2)(x-2)=x*x-2x-2x+4=x^2-4x+4

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
