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
3. Answer: a) RT
b) XZ
c) TS
4. Answer: a) 26
b) 58
c) 21.5
d) 127
<u>Step-by-step explanation:</u>
2(PT) = AE 2(CP) = AN 2(CT) = EN
2(13) = AE 2(29) = AN 2(CT) = 43
26 = AE 58 = AN CT = 21.5
Perimeter = AE + AN + EN
= 26 + 58 + 43
= 127
The third term was likely to be 25. You can see a pattern -6 when it goes up a term.
