Answer:
3
Step-by-step explanation:
Factorial means multiply that number and all numbers below it
3! = 3*2*1 = 6
0! =1
2! = 2*1 = 2
1! =1
6*1
------
2*1
6/2 =3
X^2 = 16/9
X = 4/3
Length of X is 1 1/3 inches
7. y = 1, AB = 1, BD = 10 and AD = 11
8. x = 5, AB = 20 and BC = 20
9. x= 5 and AB = 33
10. No, because AC = 12.5 while AB + BC = 20 (they should equal the same and they don't.)
Answer:
51
Step-by-step explanation:
2+2 = 4
4 - 8 = -4
-4 + 6 = 2
2 - 2 = 0
0 + 9 = 9
9 + 5 = 14
14 - 6 = 8
8 + 6 = 14
14 - 3 = 11
11 + 8 = 19
19 - 1 = 18
18 + 7 = 25
25 - 0 = 25
25 + 8 = 33
33 - 1 = 32
32 + 10 = 42
42 - 2 = 40
40 + 11 = 51
