Answer:
Integers are always closed under subtraction, addition and multiplication, not division though. Hope this helped! :D
Step-by-step explanation:
Answer = 50
Separate both into two different rectangles
Find the missing sides
Multiply (length x width)
Add the area of both the rectangles together
Example :
Top rectangle
10 - 6 = 4yd
4 x 8 = 32
Bottom rectangle
8 - 5 = 3yd
3 x 6 = 18
Area = 50
Answer:
C. 0.75
or 75%
Step-by-step explanation:
15/20 = 0.75
75%
Step-by-step explanation:
(a+b)(a+b)² = (a+b)(a²+2ab+b²)
=a(a²+2ab+b²) + b(a²+2ab+b²)
= a³+2a²b+ab² + a²b+2ab²+b³
=a³+2a²b+ a²b+ab² +2ab²+b³
=a³+3a²b+3ab²+b³
Answer:
g(n) = 0.05·2^n
Step-by-step explanation:
The paper with no folds is 0.05 mm thick. Each fold multiplies the thickness by 2, so the function is ...
g(n) = 0.05·2^n

<em>Comment on paper folding</em>
In practice, where the paper must bend around the fold, it is impossible to fold an ordinary piece of paper 9 times. You may be able to fold a very large, very thin piece of paper that many times.
