Answer:
If the two triangles are equivalent, then all the measures of triangle 2 are k times the measures of triangle 1.
This means that:
BC = k*XY
here we know that:
BC = 8
XY = 20
then:
8 = k*20
8/20 = k
0.4 = k
Then we also will have the relation:
BD = 0.4*XZ
and we know that:
BD = 6
then:
6 = 0.4*XZ
6/0.4 = XZ
15 = XZ
Answering the question, the relationship between the corresponding angle bisectors is:
BD/XZ = 6/15 = 0.4
Answer:
A. 17.5
Step-by-step explanation:
4x+8 27
L-------------M-------------------------N
<------------------ 6x -------------------->
LM = 4x+8
MN = 27
LN = 6x
LM + MN = LN
4x+8 + 27 = 6x
35 = 2x
17.5 = x
Is it number 21 you need help with?
To get the answer to this problem you first factor out the common term 2
(n+3)/(2(n-3) ) * (n+3)/(3n-9)
then factor out the common term 3
(n+3)/(2 (n-3) ) * (n+3)/(3 (n-3) )
then simplify
( (n+3)(n+3)/(2 (n-3)*3(n-3) )
Use product rule : x^a x^b= x^a+b
( (n+3)^2/(2 (n-3)*3(n-3) )
simplify 2 (n-3) * 3(n-3) to 6(n-3)(n-3)
( (n+3)^2/(6 (n-3)(n-3) )
use product rule again : x^a x^b=x^a+b
so you get the answer : ( (n+3)^2)/(6 (n-3)^2 )
so the orrect answer to this problem is answer choice (C)
