Answer:
there is 81 student and 317 adults adults :) got u
Step-by-step explanation:
4452 = 8n + (4n-7)12
4452 = 8n + 48n - 84
4536 = 56n
81 = n
Answer:
A. Line symmetry
C. Rotational symmetry ... 45°
Step-by-step explanation:
First of all, you need to have some idea what symmetry means.
A figure has <em>line symmetry</em> if it can be folded on a line and the halves of the figure lie on top of each other.
Here, any line through opposite vertices or through the midpoints of opposite sides is a line of symmetry. This figure has line symmetry.
__
A figure has <em>rotational symmetry</em> if it can be rotated by some amount less than a full turn, and it lies on top of itself. The number of times you can do this in a full turn is the degree of the symmetry.
Here, the figure can be rotated 1/8 turn (360°/8 = 45°) and it will be indistinguishable from the original. It has rotational symmetry with angles of rotation that are multiples of 45°.

<em>Comment on symmetry of regular polygons</em>
Any regular n-gon will have rotational symmetry of degree n, and symmetry about a line through its center and any vertex or side midpoint. (For odd n, such a line through a vertex goes through the midpoint of the opposite side.)

Answer:
x = 1 and x = -7
Step-by-step explanation:
x + 3 = 4
x = 1
-(x + 3) = 4
-x - 3 = 4
-x = 7
x = -7
