Complete the statement to explain why 8,000 divided by 800 = 10

2 answers:

8 0

It equals 10 because if you multiply 10 by 800 you should get 8000 because 10 multiplied by 8 is 80 so all you need to do from there is add all the zeros.

Because when you multiply by 10, it adds a zero to the end of the number, like 12*10 = 120, so vise versa for dividing

The lengths of three sides of a quadrilateral are shown below:

sasho [114]

Part A: To find the lengths of sides 1, 2, and 3, we need to add them together. We can do this by combining like terms (terms that have the same variables, or no variables).

(3y² + 2y − 6) + (3y − 7 + 4y²) + (−8 + 5y² + 4y)

We can now group them.

(3y² + 4y² + 5y²) + (2y + 3y + 4y) + (-6 - 7 - 8)

Now we simplify

12y² + 9y - 21

Part B: To find the length of the 4th side, we need to subtract the combined length of the 3 sides we know from the total length (perimeter).

(4y³ + 18y² + 16y − 26) - (12y² + 9y - 21)

Simplify, subtract like terms.

4y³ + (18y² - 12y²) + (16y - 9y) + (-26 + 21)

4y³ + 6y² + 7y - 5 is the length of the 4th side.

Part C (sorry for the bad explanation): A set of numbers is closed, or has closure, under a given operation if the result of the operation on any two numbers in the set is also in the set. For example, the set of real numbers is closed under addition, because adding any two real numbers results in another real number. Likewise, the real numbers are closed under subtraction, multiplication and division (by a nonzero real number), because performing these operations on two real numbers always yields another real number.

Polynomials are closed under the same operations as integers.
