Answer:
-3(b-3) = -3b +9
Step-by-step explanation:
-3(b-3) = -3b +9
-3 x b = -3b

From a list of ten books, 210 ways to select a group of 4 books.
What is a combination?
A combination is a selection of all or a portion of a group of items, regardless of the sequence in which the items are chosen.
The number of ways to select a group of 4 books from a list of 10 books can be calculated using the combination formula:
nCr = n! / (r! x (n-r)!)
Where n is the total number of items (in this case, 10 books) and r is the number of items to be selected (in this case, 4 books).
Plugging in the values, we get:
10C4 = 10! / (4! x (10-4)!)
= 10! / (4! x 6!)
= (10 x 9 x 8 x 7) / (4 x 3 x 2 x 1)
= 210
Therefore, there are 210 ways to select a group of 4 books from a list of 10 books.

First you have all ten books, but then every time after, you loose one because you can't put the same book in the group twice.
10 * 9 * 8 * 7 = 5040 groups

equation to use is C=cos^-1 [a^2+B^2+-2^2 /2ab
A=21
B=33
C=36
21^2+33^2-36^2
21^2=441
33^2=1089
36^2=1296
441+1089=1530
1530-1296=234
234/2=117
cos^-1*117=80.28
rounded gives you 80.3, hope this helps :D

Answer:
5
Step-by-step explanation:
To find the x-intercept of the line 4x+11y=20, we need to set y=0 and solve for x. This is because the x-intercept is the point where the line crosses the x-axis, which is the point where y=0.
First, substitute y=0 into the equation: 4x+11(0)=20
Simplify: 4x=20
Solve for x: x=5
Therefore, the x-intercept of the line 4x+11y=20 is 5.
