Step-by-step explanation:
Hello there, I think your question missed key information, allow me to add in and hope it will fit the orginal one.
Let assume the side of the cube is a units
=>The surface area of the cude is:
- A =
Given that The bottom of the cake and the area where the two cakes meet is not frosted.
=> the are of a cube that is frosted in the first layer
A' = A -
= -
=5
=> the are of a cube that is frosted in the second layer
A'' = - - (the bottom and the top of it are not frosted)
= 4
=> the total the area of the cake that is frosted is:
TA = A' + A''
= 5 + 4
= 9 square units
To solve this type of question, you just need to substitute the actual side of the cube into the expression 9 . Hope it will find you well.
Answer: What Is the question???
Step-by-step explanation:
Set up the composite function and evaluate
fg (x^2)=gx^4
4r - 8 = 5r + 12
4r - 5r = 12 + 8
-r = 20
r = -20 <===
