Answer:
n*n*n*n*n*n*n
Step-by-step explanation:
n^4 * n^3 = n^7 = n*n*n*n*n*n*n
2. Each side of a pentagon is the same size.
4cm x 5 = 20cm or 4cm+4cm+4cm+4cm+4cm = 20cm
3. Each side of a square is the same size.
13yd x 4 = 52yd or 13yd+13yd+13yd+13yd = 52yd
4. Add all sides together.
12m+12m+30m+30m = 84m
5. Again add all sides together.
16yd+16yd+4yd+4yd = 40yd
6. Each side of a square is the same size.
7in x 4 = 28in. or 7in+7in+7in+7in = 28in
7. Add all sides together.
2cm+2cm+3cm+3cm = 10cm
8. Each side of a rhombus is the same size. A rhombus has 4 sides.
23in x 4 = 92in or 23in+23in+23in+23in = 92in
9. A regular octagon has 8 sides and each side is the same size.
9cm x 8 = 72cm
Your equation is correct.

Answer:
x = 21
Step-by-step explanation:
The parallel lines divide the segments proportionally.
x/27 = 28/36
x = 27(28/36) . . . . multiply by 27 (in your head: (3·9)(4·7)/(4·9) = 3·7)
x = 21
Answer:
D 192
Step-by-step explanation:
used: new: total
4: 1 : 5
We have 240 stamps
240/5 = 48
Multiply each number by 48
used: new: total
4*48: 1*48 : 5*48
192 : 48 : 240
There are 192 used stamps and 48 new stamps in his collections
