3x=9. 3 represents the donuts she sold, x represents the cost of each donut and 9 is the total earning
If it's x²y³ then we know it's the second term of the expansion, that known we can use the combination
C(5, 2) = 5!/(2!.3!) = 10
Then if we had something like
(a + b)^5 our second term would be 10a²b³ but as we can see it's "a²"
And in our case we have 2x as a
So we must do 2² too
2² = 4
10 . 4 = 40
Then our second term of the expansion would be
40x²y³
Answer:
3/2 but if you want mixed form then 1 1/2
//
Just double check that I did the right calculations
Answer:
The first one would be corresponding angles postulate and the second one is linear pair postulate.
