7.32
10 = 73.2
100 = 732
1000 = 7320
0.006
10 = 0.06
100 = 0.6
1000 = 6
The decimal place moves to the right depending on how many zeros the number has.
For example, if you had 0.6 multiplied by 100, you would move 2 decimal places to the right because 100 has two zeros.
from second equation y = 18-x so:-
x(18 - x) = 30
x^2 - 18x + 30 = 0
x = 16.14, 1.86
when x = 16.14 y = 18-16.14 = 1.86
when x = 1.86, y = 16.14
so one variable = 16.14 and the other = 1.86 Answer
Remember that polynomials are closed under addition, subtraction, and multiplication, but they are not closed under division. The only division you have there is B; therefore the correct answer is
B.
A.

. The result is still a polynomial; therefore, answer A is incorrect.
B. 
with a remainder of 26. The result is not a polynomial anymore; therefore,
B is the correct answer.
C.

. The result is still a polynomial; therefore, answer C is incorrect.
D.

. The result is still a polynomial; therefore, answer D is incorrect.
Answer:
The answer for both apples and bananas is 21
The answer for only apples or only bananas is 45
Step-by-step explanation:
36 plus 30 minus 45
50-5 is 45
only apples or bananas is 15 + 9
three-dimensional graphs wouldn´t give you the right information but two-dimensional graphs would give you the actual size of the shape.
