You need to foil it out. That's how you get the answer.
(x+4)^20
=
(x+4) x (x+4)^19
=
(x+4)^2 x (x+4)^18
etc.
Answer:
311.02
Step-by-step explanation:
311.017 rounds to 311.02
40 - 3k + 10k = -10 - 8k - 10
40 + 7k = -10 - 8k - 10
40 + 7k = -8k - 20
40 + 7k - 40 = -8k - 20 - 40
7k = -8k - 60
7k + 8k = -8k - 60 + 8k
15k = -60
15k/15 = -60/15
k = -4
ANSWER

EXPLANATION
Given the coordinates p(2,2) and Q(3,7),
we can use the distance formula to find the distance between P and Q.
The distance formula is given by,

We substitute the coordinates to get,




Step (1) is incorrect. To divide by a number means to multiply by the reciprocal. In step (1) they did not convert the polynomial into its reciprocal.
