<h3>Logarithm and indices</h3>
Logarithm are inverse of an exponential function. Given the expression
2-2log5
This can also be expressed as;
2 - log5^2
= 2 - log 25
= log 100 - log 25
= log(100/25)
=log4
Hence the simplified form of the expression is log4

A. His answer is incorrect. 2 cubed is 2 X 2 X 2, which is 8. Add 4 and you have the answer of 12.
B. He may have multiplied 2 X 3 and then added 4, instead of multiplying 2 three times.
Set the following: Length = L Width = W
The length is twice the width: L = 2*W or: W = L/2
Perimeter: P = 60ft = 2*L + 2*W
Substituting L for W in the perimeter equation gives:
P = 60ft = 2*L + 2*(L/2) = 2*L + L = 3L
L = 60ft/3 = 20ft W=L/2=20ft/2=10ft
Verify result: Perimeter= P = 60ft = 2L + 2W = 2*20ft +2*10ft = 40ft+20ft = 60ft
The area of the rectangular is: Area = A = Length*Width = L*W = 20ft*10ft = 200 (ft)^2

Answer:
the answer is the last one, you solve this by comparing the lines from each shape. these shapes are congruent, meaning they're the same, so the like AB on the first shape and EF on the second are the same, and so on if that makes any sense. surely someone else could do a better explanation than me tho
There would be 19.2 cups. At least from what I am thinking of. So you would get 19 cups and about a fourth of another cup. I hope this helps! :)
