Hello,
Equation is y=k(x-1)²-9
and when x=0,y=-6==>-6=k*1²-9==>k=3
y=3(x-1)²-9
when y=0, 3(x-1)²-9=0
==>(x-1-√3)(x-1+√3)=0
x-intercepts are (1+√3,0) and (1-√3,0)
Answer B.
Your answer is C If not A have a good day
Answer:
21m
Step-by-step explanation:
So for the rectangle, do 5*6, and you will get the area of the whole backyard. Then to get the area of the grass, you do 3*3 to get 9.
Finally, to get the cement, you subtract the area of the grass from the area of the whole backyard so 30-9 to get 21.
5*6=30
3*3=9
30-9+21
