Answer is : \sqrt[4]{5}

Explanation: 
\frac{ \sqrt[4]{400}}{ \sqrt[4]{5}} = \frac{ \sqrt[4]{4*5*5*2*2} }{\sqrt[4]{5}}

= \frac{\sqrt[4]{5*5*2*2*4}}{\sqrt[4]{5}} =  \sqrt[4]{5*2*2*4}

= \sqrt[4]{5*2*2*4} =  \sqrt[4]{80} 
= \sqrt[4]{2*2*2*2*5}
= \sqrt[4]{2^{4}} \sqrt[4]{5}
= \sqrt[4]{5}

Express 2x^2+8x+3 in the form 2(x+p)^2+q
e-lub [12.9K]

Answer:

2(x + 2)² - 5

Step-by-step explanation:

Given

2x² + 8x + 3

To obtain the required form use the method of completing the square.

The coefficient of the x² term must be 1, thus factor 2 out of 2x² + 8x

= 2(x² + 4x) + 3

add/subtract ( half the coefficient of the x- term)² to x² + 4x

= 2(x² + 2(2)x + 4 - 4) + 3

= 2(x + 2)² - 8 + 3

= 2(x + 2)² - 5

with p = 2 and q = - 5

How many different rectangles can you draw, that has an area of 28 cm sq. ? pls help me
jolli1 [7]

Answer:

You can draw three rectangles:

1- 28 * 1.

2- 14*2

3- 7*4

Step-by-step explanation:

We have a total area of 28. If we use only integer numbers, we can find all the divisors of 28. The possible rectangles will be organized with them, taking into account that the product of them, which means the area should be 28.

28 = 1*2*2*7

We can organize them as follows:

R1: 28 = 1*28

R2: 28 = 2*14

R3: 28 = 4*7

Finally, we can conclude that there are only three possibilities

1- 28 by 1.

2- 14 by 2

3- 7 by4

The perimeters will be:

Perimeter 1 = 2x1 + 2x28 = 58

Perimeter 2 = 2x2 + 2x14 = 32

Perimeter 3 = 2x4+2x7 = 22
