Length = 4w + 2
A = length x width
= (4w + 2) . w
= 4w^2 + 2w ft square
She will have 6 braces left over since 8x8=64 and 70-64=6
Step-by-step explanation:
A.C
B.2w + 2(w + 3) = 72
2w + 2w + 6 = 72
4w + 6 = 72
4w = 72 - 6
4w = 66
w = 16.5
Answer:
22
Step-by-step explanation:
400/18=22.222222222
Round to 22
The number of times the image of the octagon will coincide with the preimage during rotation is determined by:
N = R/C
where
N is the number of times the preimage coincided with the rotated image during rotation
R is the angle of rotation
C is the central angle of the regular polygon
For an octagon, the central angle is
C = 360/8 = 45
So,
N = 360 / 45 = 8
Therefore, the rotated image of the octagon will coincide with the preimage 8 times during rotation.
