Answer:

Step-by-step explanation:
Since
have the same denominators, we add them first. We then add
to the result.
Answer:
y = 3/2x - 3
Step-by-step explanation:
Slope = 3/2
y-intercept = -3
y = mx + b
y = 3/2x - 3
20 - (4xn) = 4 is the equation
Answer:
-2, b, a+c
Step-by-step explanation:
The roots of 54 are: 1 and 54, 2 and 27, 3 and 18, 6 and 9, then it restarts all over again.
The two numbers have to multiply up to 54, and add up to 3. 9 and 6 have a difference of 3, and the multiplied sum is negative, so this is your pair.
9 and -6 fit this criteria, since they add up to 3 and multiply to 64.
