Answer:
C
Step-by-step explanation:
there is the ground line of about -5.5 to +5.5 = 11 ft.
then the 2 walls of 7 ft height = 14 ft.
that is already 25 ft.
the 2 roof sides are both a little bit longer than the corresponding ground line of 5.5ft.
so, estimated about 6ft per roof side. that adds 12 ft.
so, we are at about 37 ft.
and the closest answer is C. 36 ft.
in actual numbers a roof side is (using Pythagoras) :
roof side² = 2.5² + 5.5² = 6.25 + 30.25 = 36.5
roof side = 6.041522987... ft
so, the actual perimeter is
25 + 2×6.041522987... = 37.08304597... ft
Answer:In two similar geometric figures, the ratio of their corresponding sides is called the scale factor
Step-by-step explanation:
scale factor from the first figure to the second is always the reciprocal of the scale factor from the second figure to the first.

Who is correct?
When we apply law of indices to the above, it gives 2 multiplies by itself in 28 places
i.e.
---- in 28 places
Andre's interpretation of the expression is incorrect as:
Also, Elena's expression is incorrect.
This is so, because
<em>Hence, both of them are incorrect and I agree with none of them</em>
The product of seven and a number squared.
Remember BIDMAS or however you learned it and that indices would be calculated before being multiplied by the term in front
2c + 5c - 25 = 10
7c = 35
c = 5
the answer is c= 5
