<em>60 ; 100</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>HCF = 20 = 4×5 = 2²×5</em>
<em>LCM = 300 = 3×100 = 3×4×25 = 2²×3×5²</em>
<em>LCM/HCF = 2²×3×5²/2²×5 = 3×5</em>
<em>a = 3×hcf = 3×20 = 60</em>
<em>b = 5×lcm = 5×20 = 100</em>
<em>Good luck !</em>

12x >9(2x-3)-15
distribute
12x> 18x-27-15
combine like terms
12x>18x -42
subtract 18x from each side
12x -18x >18x-18x-42
-6x>-42
divide by -6 which will flip the inequality
-6x/-6<-42/-6
x<7

Answer:
12/13
Step-by-step explanation:
sin can be remembered by opposite over hypotenuse.
the length of the side opposite to angle B is 12, and the hypotenuse is 13. therefore, sin B will be 12/13.
