U^2(2u+3)+7(2u+3)
(u^2+7)(2u+3)
Answer:
see explanation
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition that x = 9 when y = 15
15 = 
( multiply both sides by 9 )
k = 135
y = 
← equation of variation
This is asking you to solve the equation ...
... 27 = 3^x
You can use logarithms to find
... log(27) = x·log(3)
... log(27)/log(3) = x = 1.43136376.../0.47712125...
... x = 3
Or, you can use your knowledge of small cubes and match exponents.
... 3^3 = 3^x
... 3 = x
Answer:
24 sides
Step-by-step explanation:
Step 1:
You do 180 - 165.
180 - 165 = 15
Step 2:
You do 360 divided by 15.
360/15 = 24
Step 3:
Write your answer.
Answer: 24 sides
