Real coefients
if a+bi is a root then a-bi is also a root
since 3-i is a root then 3+i s also a root
also the √7, so if √7 is a root then -√7 is also a root
so
f roots are r1 and r2 then the factored form is
f(x)=(x-r1)(x-r2)
roots are 3-i, 3+i and √7 and -√7
f(x)=(x-(3-i))(x-(3+i))(x-√7)(x-(-√7))
expanded
f(x)=x⁴-6x³+3x²+42x-70
First, divide 240 by 18 to find how many times 18 goes into 240
240/18=14 (rounded up from the original 13.3 repeating decimal because it has to do with people and you cant have a partial human and there is more than .0 there)
then multiply the number of people who do get pizza by that number
12*14=168
340 is the answer divid them by 2 and there ur answer hope it helped

Answer:
5feet per year
Step-by-step explanation:
We need to find the distance it grew in that 7 1/2 years:
63 - 25 1/2 = 37 1/2
Now to find the average yearly growth we can divide this by 7 1/2:
37.5 ÷ 7.5 = 5
So the yearly rate of growth of the tree is 5f/y
