Answer:

\frac{\sqrt[3]{20}}{5}

Step-by-step explanation:

Let x = \sqrt[3]{\frac{4}{25}}, we proceed to show the procedure to determine the simplest form of this number:

1) \sqrt[3]{\frac{4}{25} } Given.

2) \left(\frac{4}{25}\right)^{1/3} Definition of cubic root.

3) [4\cdot (25)^{-1}]^{1/3} Definition of division.

4) (4)^{1/3}\cdot [(25)^{-1}]^{1/3}  a^{c}\cdot b^{c} = (a\cdot b)^{c}

5) \{(4)^{1/3}\cdot [(25)^{-1}]^{1/3}\} \cdot \{[(25)^{-1}]^{2/3}\cdot [(25)^{-1}]^{-2/3}\} Modulative and associative properties/Existence of multiplicative inverse/a^{b}\cdot a^{c} = a^{b+c}

6) \{(4)^{1/3}\cdot [(25)^{-1}]^{-2/3}\}\cdot \{[(25)^{-1}]^{1/3}\cdot [(25)^{-1}]^{2/3}\} Commutative and associative properties

7) \{(4)^{1/3}\cdot [(25)^{-1}]^{-2/3}\}\cdot (25)^{-1}  a^{b}\cdot a^{c} = a^{b+c}

8) [(4)^{1/3}\cdot (25)^{2/3}]\cdot (25)^{-1}  (a^{b})^{c} = a^{b\cdot c}

9) [4\cdot (25)^{2}]^{1/3}\cdot (25)^{-1} (a^{b})^{c} = a^{b\cdot c}/a^{c}\cdot b^{c} = (a\cdot b)^{c}

10) (2500)^{1/3}\cdot (25)^{-1} Definition of power and multiplication.

11) [(125)\cdot (20)]^{1/3}\cdot (25)^{-1} Definition of multiplication.

12) (125)^{1/3}\cdot [(20)^{1/3}\cdot (25)^{-1}] a^{c}\cdot b^{c} = (a\cdot b)^{c}/Associative property.

13) 5\cdot [(20)^{1/3}\cdot (25)^{-1}] Definition of cubic root.

14) 5\cdot [(20)^{1/3}\cdot (5)^{-1}\cdot (5)^{-1}] Definition of multiplication/a^{c}\cdot b^{c} = (a\cdot b)^{c}

15) [(20)^{1/3}\cdot (5)^{-1}][5\cdot (5)^{-1}] Commutative and associative properties.

16) (20)^{1/3}\cdot (5)^{-1} Existence of multiplicative inverse/Modulative property

17) \frac{\sqrt[3]{20}}{5} Definitions of cubic root and division/Result

Explain how to use a cordinate plane to find the area of a rectangle with vertices (-4,9) (-4-3) (-1,-3) and(-1,9) . What is the
PolarNik [594]

Answer:

The Area of the rectangle is 36

Step-by-step explanation:

One can use the vertices of the rectangle in coordinate form, by observing that (please see image attached):

(1) the distance between x-coordinates that share the same y-value give the length of the segments that define the horizontal sides of the rectangle,

(2) and the distance between y-coordinates that share the same x-value give the length of the segments that define the vertical sides of the rectangle,

Therefore, as an example of statement (1) above, the distance between the x-coordinates of : (-4,-3) and (-1,-3) which share the same "y-value" -3, is:

| -1 - (-4)| = |-1+4| = |3| = 3 which is the length of the horizontal side of the rectangle (the base of the rectangle).

As an example of statement (2), the distance between the y-coordinates of: ((-1,-3, and (-1,9) which share the same "x-value" -1, is:

| 9-(-3)| = |9+3|=|12|=12 which is the length of the vertical side of the rectangle (the height of the rectangle).

So, the area of the rectangle which is defined as the product of its base times its height, is given by:

Area=base\,*\.height\,= 3\,*\,12\,= 36

What number should be added to -20 to get the sum of 36?
DochEvi [55]

36 - (-20) = 56

SO the number that should be added to -20 to get the answer of 36 is 56.

Hope this helps! Mark as Brainliest please! :)))
