<h3>
Answer: 35 inches</h3>
Each side of the pentagon is multiplied by 5/3 to get the length of each new side, so the perimeter is multiplied by 5/3 to get the new perimeter.
New perimeter = (scale factor)*(old perimeter)
New perimeter = (5/3)*(old perimeter)
New Perimeter = (5/3)*(21)
New Perimeter = (5/3)*(21/1)
New Perimeter = (5*21)/(3*1)
New Perimeter = 105/3
New Perimeter = 35 inches
N, O, S, and Z all have rotational symmetry
When you simplify 3/12, it's 1/4.
h/8 is equal to 1/4 so you want to multiply 2 for 1/4 which it becomes 2/8
Therefore h is 2
It’s the second one, 65.4

√52 -√13 +√117
= 2√13 -√13 +3√13
= 4√13 . . . . matches selection A
_____
√52 = √(4·13) = (√4)(√13) = 2√13
√117 = √(9·13) = (√9)(√13) = 3√13
