Answer:
C: 11.5 cm, 4.2 cm, 7.6 cm
Step-by-step explanation:
In order for the lengths to form a triangle, the sum of the shortest two must exceed the longest.
A. 5.4 +5.4 = 10.8 < 12.6
B. 1.3 +5.9 = 7.2
C. 4.2 +7.6 = 11.8 > 11.5 . . . . will make a triangle
D. 3.1 +6.6 = 9.7 < 10.4
Answer:
The other factor is 
Step-by-step explanation:
we know that
In this problem we have
and
-----> because is a factor
substitute and solve for b
so
Verify in the second equation

-----> 
--> is ok
The other factor is
Answer:
1/2
Step-by-step explanation:
0.5 is also the same as 1/2 in simplest form.
A8% is X
10% is 700-X
X(.08)+ .10(700-X)= 64
.08x+ 70-.10X=64
-.02X+70=64
-70=-70
-.02x= -6
Divide by -.02
X= 300
Answer $300 was invested at 8%
Check 300 times .08= 24. 700-300=400 times .10 = 40 and 24+40=64
4(2m-1)=16
8m-4=16
8m=20
m=20/8
=2.5
Hope this helps. Just ask if you need a better explanation.
