Answer:
49 units
Step-by-step explanation:
Given the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
22BC = 484 ( divide both sides by 22 )
BC = 22
------------------------------------------------
Similarly
=
, substitute values
=
( cross- multiply )
22AC = 352 ( divide both sides by 22 )
AC = 16
Thus perimeter of Δ ABC is
perimeter = AB + BC + AC = 11 + 22 + 16 = 49 units
Let's replace every copy of x with 7 and simplify.
Which is clearly false. This is probably the set of steps you followed to get "no solution".
Why is there no solution? Well let's subtract 9 from both sides to isolate the square root
Recall that the result of a square root operation is never negative. The range of and
is the set of nonnegative numbers. There is no way we can have the left hand side result in -6
If there was a negative sign out front the square root and we have this instead
then the answer would be x = 7
Unfortunately, there isn't such a negative sign, so we stick with "no solutions".
