If the length of a rectangle in terms of x is 5x2 + 3x + 6, and its width is 7x +
9, what is the perimeter of this rectangle? Don't leave any spaces in your
solution.
Perimeter:_ units
A.20x2+20x+30
B.10x5+20x+30
C.10x2+2x+3
D.10x2+20x+30

10x²+20x+30

Step-by-step explanation:

formula of perimeter of rectancle=2(l+b)

put values

2(5x²+3x+6+7x+9)

2(5x²+10x+15)

2(5x²)+2(10x)+2(15)

10x²+20x+30

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
