Answer:
Step-by-step explanation:
y=x² +8x +7
first parabola opens up because variable a is positive
the axis of symmetry = =4 ( which is the case or have of the vertex)
v(h,K)
h=-b/2a = -8/2(1)=
h=-4
vertex(-4,-9)
focus(-4,-35/4)
diretrix : y = -37/4
12 days
420/35 to find amount of days to finish book
420/35 = 12
Answer: 2/3 multiply that by 15 and you get 30/3 witch simplified is 10
16
(9 + radical - 4) - (5 + radical - 16)
9 + radical - 4 - 5 - radical + 16
9 - 4 - 5 + 16 + radical - radical
= 16
maybe you will sort the questions out?
