because 2*2 is 4 and 7*2 is 14
Sec x = 1/Cosx
Pi radians = 180 degress
Pi/12 = 180/12 = 15 degrees.
Sec15° = 1/Cos15°
Sec pi/12 = Sec 15° = 1/Cos 15°
Cos 15° = 0.9659 using a calculator.
Sec pi/12 = Sec 15° = 1/Cos 15° = 1/0.9659 = 1.0353
Sec Pi/12 = 1.0353
Answer:
Answers are all the way to the right
Step-by-step explanation:
3(a+b) 3(5 + 3) 3(8) 24
(a+b)-7 (5 + 3) - 7 8 - 7 1
4(2a+b) 4(2*5 + 3) 4(10 + 3) 4(13) 52
6( a- b )+5 6(5 - 3) + 5 6(2) + 5 12 + 5 17
( a + b) ( a -b ) (5 + 3)(5 - 3) 8(2) 16
(2a + b ) (2a - b) (2*5 + 3)(2*5 - 3) (10 + 3)(10-3) 13(7) 91
3 ( b + a ) 3(3 + 5) 3(8) 24
4 (b + 2a) 4(3 + 2*5) 4(3 + 10) 4(13) 52
