There are a couple of ways you can solve this. You can write it out like
(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)
And pretty much use the foil method
Or you can use the binomial theorem (google it if you dont know)
The solution should be:
(K^7) - 21(k^6) + 189(k^5) - 945(k^4) + 2835(k^3) - 5103(k^2) + 5103k - 2187
Answer:
4.5
Step-by-step explanation:
Well, she runs 3
miles in 28 minutes.
42
=
28
⋅
1.5
So, her journey would just be running
1.5
times, with each time running
28
minutes.
So, she runs a total of
1.5
⋅
3
=
4.5
miles
Answer:
d. 23
Step-by-step explanation:
x: small hat
y: medium hat
z: large hat
We now write the system of equations:
x + y + z = 47
5.50x + 6y + 7z = 302
-3x + y = 0
We can write the system in matrix form as:
Ax = b
Where,
A = [1 1 1; 5.50 6 7; -3 1 0]
b = [47; 302; 0]
x = [x; y ; z]
Solving the system we have:
x = 6
y = 18
z = 23
hope this helps
