The distance between A and B is d = |B - A|
We have d = 3 and A = 12.
Substitute:

<h3>Answer: 9 and 15.</h3>
2m + 2p = 16 Subtract 2m from both sides
2p = 16 - 2m Divide both sides by 2
p = 8 - m
Answer:
(x + 3)(x + 7)
Step-by-step explanation:
Find two numbers that when added up to , they ALSO have to multiply up to 21. This is simple because of the fact that there is no leading coefficient greater than 1⃣.
Set each set of parentheses to 0 and solve for x.
X—6 = 0
X = 6
X + 5 = 0
X = -5
X-9 = 0
X = 9
The zeros are 6, -5, 9
4d=56
d=14. Ad a result, Dorothy is 14 years old. Hope it help!
