Find the vertex by completing the square to answer both a and b
d)
x-ints is when y=0
so use quadratic equation for
b^2-20b+200=0
a=1
b= -20
c=200
But notice these imaginary numbers means 0 x intercepts.

Answer: 1.6 lawns a week
Step-by-step explanation:
Carlt mowed 2 more lawns than Rocco every week for 5 weeks.
This means that the number of lawns he mowed more than Rocco is:
= 2 * 5
= 10 lawns
If Carlt mowed 18 lawns in those 5 weeks then Rocco mowed:
= 18 - 10
= 8 lawns
Lawns mowed per week by Rocco:
= 8/5
= 1.6 lawns a week
