Question

ER

Answer 1

okay dude for similar shapes we have :
\[\frac{ area1 }{ area2 }=(\frac{ side2 }{ side2 })^{2}\]

Answer 2

can you solve for the missing variable now ? or still need another hint

Answer 3

i guess i can :)

Answer 4

great then, can you now give the answer for 14?

Answer 5

121/11=18/12

Answer 6

\[\frac{ 121 }{ x }=(\frac{ 18 }{ 12 })^2\rightarrow \frac{ 121 }{ x }=(\frac{ 3 }{2})^2\]
easy now right ?

Answer 7

yesss veryy easy , is that how i solve all of itt

Answer 8

do i keep it raised to the powerr

Answer 9

no actually you will distribute the power and solve for the variable.
I did not actually read the rest ,but that's idea hold for 13 an 14 ,but I'm pretty much sure you will solve the rest just as easy :)

Answer 10
