Find the value of X<br> (Simplify your answer. Type an exact answer, using radicals as needed.)

Gala2k [10]

Answer:

11 $\sqrt{2}$

Step-by-step explanation:

The given shape is a right triangle, to find the value of x we can use Euclidian Theorem:

x^2 = 14*(14+4)

x^2 = 280 find the root for both sides

x = 11 $\sqrt{2}$

two time the quantity of seven less than one fourth is equal to four more than one third of the number. what is the number

kari74 [83]

Answer:

2(7) - 1/4 = 4 + 1/3x

x = 117/4

Step-by-step explanation:

solving an equation with one missing variable

step 1: multiply 2 * 7

ex: 14 - 1/4 = 4 + 1/3x

step 2: subtract 14 from 1/4

ex: 55/4 = 4 + 1/3x

step 3: subtract 4 from both sides of the equation

55/4 - 4 = 4 + 1/3x - 4 (39/4 = 1/3x)

step 4: divide both sides of the equation by 1/3

ex: 39/4 / 1/3 = 1/3x / 1/3 (x = 117/4 or x = 29 1/4)

step 5: to check your answer add the answer you got from the last equation which was 117/4 or 29 1/4 and input it into the original equation and get your final answer

ex: 2(7) - 1/4 = 4 + 1/3(117/4)

14 - 1/4 = 4 + 39/4

55/4 = 55/4 (if both sides of the equation are the same numbers like 55/4 = 55/4 then your answer is true)

$i^5+i^{-25}+i^{45}$<img src="https://tex.z-dn.net/?f=%24i%5E5%2Bi%5E%7B-25%7D%2Bi%5E%7B45%7D%24" id="TexFormula1" title="$i^5+i

gregori [183]

$i^5+i^{-25}+i^{45}$

Rewrite the term $i^{-25}$

$=i^5+\dfrac{1}{i^{25}}+i^{45}$

Expand each term so we have

$=i(i^2)^2+\dfrac{1}{i(i^2)^{12}}+i(i^2)^{22}$

Use the fact that $i^2=-1$

$=i(-1)^2+\dfrac{1}{i(-1)^{12}}+i(-1)^{22}$

Use the fact that $(-1)^{a}=1$ when a is an even number

$=i+\dfrac{1}{i}+i$

Simplify

$=i-i+i$

$=i$

Let me know if you need any clarifications, thanks!
