name the lengths of the sides of three rectangles with a perimeter of 12 units use only whole numbers

1 answer:

8 0

The perimeter of a rectangle is 2(w+l)
We can find the lengths by setting the equation equal to 12.
12=2(w+l)
12÷2=(2(w+l))÷2
6=w+l
6=1+5
6=2+4
6=3+3
These are the lengths of the sides of three rectangles with a perimeter of 12 units.
You're probably wondering why the third one has two of the same number, because that's usually how the lengths of sides of squares are, not rectangles.
Well, there's this wonderful thing about the rules of shapes.
Squares ARE rectangles.
Because they follow the rules for a rectangle, squares are also classified as rectangles.
So, the rectangle side lengths are as follows:
1 unit by 5 units
2 units by 4 units
3 units by 3 units

-84 > -6(2 - 3b) Please show work!!

mart [117]

-84 > -6(2 - 3b)

Distributive property.

-84 > -12 + 18b

Add 12 to both sides.

-72 > 18b

Divide both sides by 18.

-4 > b

The value of b is less than -4

Classify the number as natural, whole, integer, rational, and/or irrational.

adelina 88 [10]

This number is natural, whole, integer, and rational.

Whole numbers are numbers such as 0, 1, 2, ... This is a whole number.

Natural numbers can also be counting numbers. They are the whole numbers, but starting at 1, not 0. This is a natural number.

Integers are whole numbers with negatives. This is an integer.

Rational numbers are any numbers that can be written as a fraction. We can write this as 4563/1, so it is rational.

Answer:

C. x - 4

Step-by-step explanation:

The best way to do this is to first take out GCF

6(x² - x - 12)

Then we factor

6(x - 4)(x + 3)

We can now see our answer.

By using a number line, arrange each of the each of the following in descending order (a) 4 29upon 33, -2.365,5.5,-3 upon 4 (b)

Sergeeva-Olga [200]

The arrangement of the numbers in descending order (largest to smallest) are as follows;

a). 5.5, 4, 29/33, -3/4, -2.365
b). 10, 5.855, 5/8, 1/2 -2π, -8

<h3>What is the arrangement of the numbers in descending order in each case?</h3>

It follows from convention that the positive numbers are larger than negative numbers and hence, should appear before negative numbers when the arrangement is in descending order.

Consequently, the numbers can be evaluated and arranged as in the answer above with positive numbers increasing rightwards and negative numbers decreasing leftward of 0 on the number line.
