If the area A of a triangle is 72, and the height h is equal to the length of the base b, what is the length of the base? A= 1/2 bh

Select one
A. 9
B. 12
C. 11
D. 5

option B

Step-by-step explanation:

let the height=x

base=x

Area=½bh

72=½x•x

72×2=x²

144=x²

x=√144=12

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

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
