All you do is divide -12/20 by 4/4 which is -3/5
2/15
90 ÷ 6 = 15
Theoretical probability would be 15 due to the equation above
Question 13: The answer is D
Question 7: The answer is C
Question 14: The answer is B
And the question for the last Pic, the correct graph is B.
The greatest common factor is 8
Answer:
B.) why Factor p+ 12r - 6, I did not do that below.
Step-by-step explanation:
r^2+12r-6=0
solve:
r^2 + 12 r + 36 - 36 - 6 = 0
factor the trinomial by completing the square.
( r + 6)^2 -42 = 0
(r + 6)^2 = 42
r + 6 = root(42 ) or r + 6 = - root(42)
r = -6 + root(42) or r = -6 -root(42)
