The dimensions of a playground are represented by a width of 10x+2 feet and a length of 5x -5 feet. Write an expression that represents the area of the playground?
A.50x^2+30x+4
B.50x^2-40x-10
C.50x^2+40x+10

B) 50x^2-40x-10

Step-by-step explanation:

Assuming that the playground is rectangular, A=L•W

A=(5x-5)(10x+2) Use the FOIL method

= 50x^2+10x-50x-10 Combine like terms

= 50x^2-40x-10

B) 50x^2-40x-10

Step-by-step explanation:

Assuming that the playground is rectangular, A=L•W

A=(5x-5)(10x+2) Use the FOIL method

= 50x^2+10x-50x-10 Combine like terms

= 50x^2-40x-10

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

54.864 meters
