Answer:

Option B.

Explanation:

It is given that the perimeter of the parallelogram ABCD is 30 cm.

Let measure of AB is x cm.

AD 3 cm more than twice AB.

AD = 2x + 3

Perimeter of ABCD is

Perimeter=2(AB+AD)

30=2(x+2x+3)

30=2(3x+3)

30=6x+6

30-6=6x

24=6x

Divide both sides by 6.

4=x

The measure of AB is 4 cm.

Hence, the correct option is B.

valentina_108 [34]

answer:

There is no concrete evidence to prove whites are most favorable however, because whites have been the major source of advertisements it almost proves the statement true. Nonetheless, their only reason is whites are more stable and are more likely to offer the media with more money power than any other group of people in the U.S. “When people of color appeared in ads, they often had peripheral roles, appearing in non-speaking “background” roles” (Henderson and Baldasty 2003:102).

Most white characters held the speaking roles in the commercial as the African-Americans characters were the ones in the restaurant in the background (Henderson and Baldasty 2003: 102). In the Henderson and Baldasty article it states that the ads that whites and people of color relates back to the cost or view of the product being advertised. People of color who are in the primary roles of an advertisement are often related back to products that are less expensive like fast food advertisement. Whites in the other hand with primary roles tend are most likely advertising products most associated with most upscale products like cooking at home or expensive cars (Henderson and Baldasty 2003). The media has been a part of the daily life of the American people for the longest time, because of this fact, the media influences the decisions and views of how people should live.

As a result other races and ethnic groups other than white Americans are often put
