THANK U SO MUCH HAVE A HAPPY HOLIDAY!!
Answer:
ummmm..... let's see..
Step-by-step explanation:
using "Almighty formula"
{Y = –x +/– √b^2 – 4ac / 2a}
so we name all the values behind the coefficients which are; –1^2, 8 and 11
so let's assign a,b,c to these values:
a =–1, b =8, c = 11
all you just do now is to add these values to the formula
you should be having Y =1 +/– √8^2 – 4×–1×11
———————————
2×–1
Y =1 +108
———— or Y = 1–108
–2 –––––
–2
now add and divide to get Y.
(your answer will be two)

Step-by-step explanation:
you have to use distributre property to find this ( hope this helps )
Answer:
B,C
Step-by-step explanation:
1. (8+4) x 2 = 8 + (4 x 2)
(12) x 2 = (8) + 8
24= 16 - not true
2. When you distribute you times everything in the parenthese with the number on the outside.
Answer:
a. 9
b.
c.
d.
Step-by-step explanation:
a. The total number of balls in the bag is
b. Let A denote the event that the 1st chosen ball is orange. Let B denote the event that the 2nd chosen ball is orange.
c. If the first choice is orange, (i.e A occurs) then there are 9 - 1 = 8 balls left in the bag with 3 - 1 = 2 orange balls.
d. Here we are required to compute . We use the fact that
