Answer:

9

Step-by-step explanation:

Area is measured in square units. For example in the rectangle above, if the sides are 2 and 4 meters long, then the area is 8 square meters. If the sides were 2 feet and 4 feet long the area would be 8 square feet. The most important thing to remember when calculating area is that.

RUDIKE [14]

Answer:

Step-by-step explanation:

If p  million was the population in 1950 the equation is:

5p + 2 = 18.5

5p = 16.5

p = 16.5 / 5

p =  3.3 million.

Can someone help me with this part of my homework? I'll give 10 points in exchange! ^_^
Advocard [28]

19. 5/11

20. 6/10

21. 4/11

22. 10/15

23. 11/11

You can use a calculator for the decimal part: just divide the numerator into the denominator. :) Since you're in middle school, you probably already know what repeating or terminating decimals are. If you don't, just search up the definitions. :) (BTW the / means over. i.e.: 11/11 = eleven over eleven)
