Answer:
4. 56 ft²
Step-by-step explanation:
SA = (4×4)+(4×½×4×5)
= 16+40
= 56
The answer is 42 because that is half of 84 and 31 of the muffins were banana which is half of 62
Area is the length times the width.
When you know the area and one of the dimensions, divide the area by the known dimension to find the other one.
133 / 11 = 12.09
The room needs to be at least 12.09 feet wide. ( round answer if needed).

Answer:
See proof below.
Step-by-step explanation:
True
For this case we need to use the following theorem "If
are eigenvectors of an nxn matrix A and the associated eigenvalues
are distinct, then
are linearly independent". Now we can proof the statement like this:
Proof
Let A a nxn matrix and we can assume that A has n distinct real eingenvalues let's say 
From definition of eigenvector for each one
needs to have associated an eigenvector
for 
And using the theorem from before , the n eigenvectors
are linearly independent since the
are distinct so then we ensure that A is diagonalizable.
