Reema and sohini bought (x^2 - 9) mangoes. they divided into (x+3) groups. each group has three rotten mangoes. how many good mangoes does each group contain? pls give me answer

x - 6

Step-by-step explanation:

divide number of mangoes bought by number of groups, that is

= ← numerator is difference of squares

cancel the factor (x + 3) on numerator/denominator

number in each group = x - 3

subtract 3 rotten mangos from group for good mangoes

good mangoes = x - 3 - 3 = x - 6

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
