Answer:
Step-by-step explanation:
2(9x+1)+88=180
9x+1+44=90
9x=90-45=45
x=5
The mean will always equal 0.
The variable for the mean is μ
9515 1404 393
Answer:
(d) Reflexive Property of ≅; SSS
Step-by-step explanation:
There are no angles involved in the proof, so the SAS claims do not apply.
__
The symmetric property says ...
if A ≅ B, then B ≅ A
The reflexive property says ...
A ≅ A
In this case, the reflexive property is the one being invoked in the statement ...
AC ≅ AC
That, together with the claims of line 3 concludes the claim that all three sides are congruent to their corresponding counterparts. Hence the SSS postulate applies.
It is 23a+72
see
6(-3a+12)+8a-13a
-18a+72+8a-13a
23a+72
