We know -48 came from (a)(-6), the "L" in "FOIL".
If -48 = -6a, then a = 8.
Now with a=8, go ahead and FOIL (x+8)(x-6) to find m.
Answer:
15/121.
Step-by-step explanation:
Probability of picking a red = number of reds in the bag / total number of marbles in the bag
= 3 / (3 + 3 + 5)
= 3/11.
Probability of picking a blue = 5/11.
These 2 events are independent so we multiply probabilities, therefore the
Probability of (a red then a blue) = 3/11 * 5 /11
= 15/121.
Add 7 on both sides to then left side cancels out and you end up with 13x=143 then you divide 13 on both sides and get x=11
Answer:
c. 5/6 = [ g(7) − g(4) ] / (7 − 4)
Step-by-step explanation:
C. 6 2/12 because you put the common denominator (12) by multiplying 1/4 x 3/3 then add it to get 5 14/12 or 6 2/12
D.5 2/15
