Surface area = 52mi

Step by step:

The equation is 2(wl+lh+hw),

Replace the letters by the corresponding numbers 2(2•1+8•1+8•2),

Simplify it to 2(2+8+16)

Add everything in the parenthesis 2(26)

Multiply 2 by 26, giving you 52.

The friend is incorrect because 2 translations would just move the shape to a different area, then a reflection would reflect it.

Long story short: if you do to translations that only move in one direction for ex. X+10 y+ 0 then it will be a glide reflection

A = 180 - 143 = 37
b = 143
c = a = 37
e = a = 37
f = 90 - 37 = 53
d = 180 - 85 - 37 = 58
g = 48
h = 180 -48 -48 = 84
k = 180 -84 = 96
m = 180 - 58 - 96 = 26
p = 180 - 26 - 85 = 69
r = 180 -69 = 111
s = p = 69

Answer:

Explanation:

3. Find LCM of (30, 9):

30 = 2 x 3 x 5
9 = 3 x 3

Thus : LCM(30, 9) = 2 x 3 x 3 x 5 = 90

Therefore, in 90 days he will has both activities again.

4. Determine whether its possible to construct a triangle with the given length.

a.
8 + 9 > 11 (true)
8 + 11 > 9 (true)
9 + 11 > 8 (true)

Thus 8,9 and 11 can be construct as a triangle.

b.
4 + 5.1 > 12.5 (false)
4 + 12.5 > 5 (true)
12.5 + 5 > 4 (true)

Thus, 4, 5.1 and 12.5 cannot be constructed as a triangle.
