Can anyone assist me with these?

Option A. Distributive Property,

Option B. Commutative Property,

Option C. Associative Property,

Option D. Associative Property

Step-by-step explanation:

Consider the first example, 3( x + 3 ) = 3x + 9. We can note that in order to derive " 3x + 9 " you had to distribute the 3 to x and 3 in ( ), as demonstrated below;

And hence, this would be a perfect example of the distributive property.

_________________________________________________

Now this second example, 2 + 3 + 4 = 4 + 3 + 2 is simply the re - arrangement of numbers;

...And is thus the perfect example of the commutative property.

_________________________________________________

This third example we have an application of the associative property. The numbers are again being re - arranged and grouped, but with a multiplication sign between them.

_________________________________________________

Last but not least the associative property. We have the grouping of numbers with a plus sign between, which indicates the associative property of addition.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
