Determine the probability of getting a red chair, next.
First, we nee the total number of chairs


Probability of getting red is then calculated as thus;



Answer:
27 and 29
Step-by-step explanation:
let A and B the expected numbers
assuming B = A + 2, the problem can be written as follows
¼(A + A + 2) = 14
4*¼(A + A + 2) = 4*14
(A + A + 2) = 56
2A + 2 = 56
A + 1 = 28
A = 27
B = 27 + 2 = 29
−(x^2−6x+7) that is the answer
C. The corresponding sides of a triangle have the same slope
