Answer:
This might be permutation promblem srry if im wrong.
P(6,3)=6x5x4=120
P(4,2)=4x3=12
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
Answer:
No relationship

Answer:
9
Step-by-step explanation:
BECAUSE 54 : 2,3,9. and 45 : 5,9. so the greatest common factor is 9

The number of different ways that this could play out is
(7 x 6 x 5 x 4 x 3 x 2 x 1) = <em>5,040</em>
