Answer: c. OSRN
Step-by-step explanation:
Sides of similar shapes are proportional.
For Rectangle LOSP,
Length = LO = 4+6+8 = 18 units
Width = OS= 12 units
Here,
[proportionality constant]
a. For Rectangle LMQP,
Length = MQ = 12 units
Width = LM = 4 units
Here, 
LMQP is not similar to LOSP.
b. Similarly, for LNRP,
Width = LN= 4+6 = 10
length = NR = 12

LNRP is not similar to LOSP.
c. For OSRN,
Length = OS = 12
Width = ON = 8

OSRN is similar to LOSP.
d. For MNRQ,
Length= NR = 12
Width = MN = 6

MNRQ is not similar to LOSP.
Hence, the shape similar to rectangle LOSP is OSRN.
Answer: a = 
Step-by-step explanation:
Rewrite the equation as 4a + 9ab=K
Factor out a of 4a + 9b
a (4 + 9b) = K
divide each term by 4 + 9b and simplify
=
If you give me the equation I can simply it for your
Cos(5/12)=65.4
It won't let me do short anwser
The quotient will be less that 34 because 78 divided by 34 is 2
