Answer:

x^4 + x^2 + 1/4

Step-by-step explanation:

{( {x}^{2}  +  \frac{1}{2} })^{2}

a = x^2

b = 1/2

{a}^{2}  + 2ab +  {b}^{2}

({x {}^{2}) }^{2}  + 2( {x}^{2} )( \frac{1}{2} ) +  { \frac{1}{2} }^{2}

{x}^{4}  +  {x}^{2}  +  \frac{1}{4}

9 stores is 3% of how many stores?
hichkok12 [17]
Hello there! We can solve this question by writing and solving a proportion. Set it up like this:

9/x = 3/100.

This is because 9 is 3% of x number of stores and percents are parts of 100. Setting it up like this will help us get the correct answer. Cross multiply the values . 9 * 100 is 900 and 3 * x = 3x. You get 900 = 3x. Now, divide each side by 3 to isolate the x. 3x/3 cancels out the x. 900/3 is 300. There. x = 300. 9 stores is 3% of 300 stores.

Simplify your answer
Lelechka [254]

Answer:

<h2><u>0</u></h2>

Step-by-step explanation:

If 2u-6=4, let's solve for u.

Add 6 to both sides

2u-6+6 = 4+6

Simplify

2u = 10

Divide both sides by 2

u = 5

Now, we can solve u-5

5-5 = 0

Find the perimeter of rectangle whose length is 40 and the diagonal is 41 cm<br>​
Bond [772]

Answer:

<h2>              P = 98 cm</h2>

Step-by-step explanation:

Given one side and diagonal of rectangle we can use Pythagorean theorem to calculate the other side of it.

L=40\, cm\\D=41\,cm\\W=\ ?\\\\W^2+L^2=D^2\\\\W^2+40^2=41^2\\\\W^2+1600=1681\\\\W^2=81\\\\W=9

Perimeter:

P = 2W + 2L = 2•40 + 2•9 = 80 + 18 = 98
