What is the definition of a four-dimensional (4-D) shape?

Answers

A four-dimensional space or 4D space is a mathematical extension of the concept of three-dimensional or 3D space. Three-dimensional space is the simplest possible generalization of the observation that only three numbers, called dimensions, are needed to describe the size or position of objects in the everyday world. For example, the volume of a rectangular box is found by measuring its length (usually labeled x), width (y), and depth (z).

Answers

Answer:

6 2/3 = x

Step-by-step explanation:

24 1/14 + 8 3/7  = (x ÷ 1 1/9) * 5 5/12

Add on the left by getting a common denominator

24 1/14 + 8 3/7*2/2  = (x ÷ 1 1/9) * 5 5/12

24 1/14 + 8 6/14  = (x ÷ 1 1/9) * 5 5/12

32 7/14  = (x ÷ 1 1/9) * 5 5/12

32 1/2 =  (x ÷ 1 1/9) * 5 5/12

Changing to improper fractions

(2*32+1)/2 = (x ÷ 10/9) * (12*5+12)/12

65/2 = (x ÷ 10/9) * (65)/12

Multiply each side by 12/65

65/2 * 12/65 = (x ÷ 10/9) * (65)/12*12/65

6 = (x ÷ 10/9)

Copy dot flip

6 = x * 9/10

Multiply by 10 /9

6 * 10/9 = x * 9/10 * 10/9

60/9 =x

20/3 =x

Changing back to a mixed number

3 goes into 20 6 times with 2 left over

6 2/3 = x

Answer:

[tex]\frac{20}{3}[/tex]

Step-by-step explanation:

[tex](24+8)+(\frac{1}{14} +\frac{3}{7})=(x:\frac{10}{9}).\frac{65}{12}\\32+\frac{1}{2}=(x.\frac{9}{10}) .\frac{65}{12} \\32\frac{1}{2}=(\frac{9}{10}x).\frac{65}{12} \\\frac{65}{2}=\frac{9}{10}x.\frac{65}{12} \\\frac{65}{2}=\frac{3}{2} x.\frac{13}{4} \\\frac{65}{2} =\frac{39}{8} \\\frac{20}{3} =x\\x=\frac{20}{3}[/tex]

Simplify the expression by combining like terms: x + 7x

Answers

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

Step-by-step explanation:

Answer:

[tex]8x[/tex]

Step-by-step explanation:

[tex]x+7x[/tex]

[tex]8x[/tex]

The answer is [tex]8x[/tex] when you simplify because you are adding another [tex]x[/tex] to [tex]7x[/tex] so it becomes [tex]8x[/tex]

Part B: Show that one of your expressions in Part A is equivalent to the given expression using algebraic properties. Explain which properties you used. (4 points)

Part C: Show that your other expression from Part A is equivalent to the given expression by substituting a number for m. (3 points)

Answers

Answer:

See below.

Step-by-step explanation:

Part A:

4(m + 3 + 5m) =

= 4m + 12 + 20m

4(m + 3 + 5m) =

= 4(6m + 3)

Part B:

Use the distributive property on the given expression to get the first expression.

4(m + 3 + 5m) =

= 4 * m + 4 * 3 + 4 * 5m

= 4m + 12 + 20m

Part C:

Let m = 2

a. Substitute 2 for m in the original expression:

4(m + 3 + 5m) =

= 4(2 + 3 + 5 * 2)

= 4(5 + 10)

= 4(15)

= 60

b. Substitute 2 for m in the second equivalent expression of part A.

4(6m + 3) =

= 4(6 * 2 + 3)

= 4(12 + 3)

= 4(15)

= 60

By substituting 2 for m, both expressions evaluate to 60.

Part A: 24m+12, 12(m+2)
