Answer:

The answer is B (1 , 3) , (2 , 6) , (4 , 12) , (5 , 15)

Step-by-step explanation:

∵ X : 1 , 2 , 4 , 5

∵ Y : 3 , 6 , 12 , 15

∵ 2/6 = 1/3

∵ 4/12 = 1/3

∵ 5/15 = 1/3

∴ 1/3 = 2/6= 4/12 = 5/15 = 1/3 ⇒ all are proportion

∴ Answer B is in proportional relationship

Answer:

$\hookrightarrow \sf x^6+24x^5+240x^4+1280x^3+3840x^2+6144x+4096$

solving steps:

$\rightarrow \sf (x + 4)^6$

$\bold{rewrite \ the \ following}$

$\rightarrow \sf (x + 4)^2 (x + 4)^2 (x + 4)^2$

$\bold {formula \ used : \sf (x+a)^2 = (x^2 + 2xa + a^2)}$

$\rightarrow \sf (x^2 + 8x+16) (x^2 + 8x+16) (x^2 + 8x+16)$

$\bold{simplify \ by \ removing \ parenthesis}$

$\rightarrow \sf (x^4 +8x^3 + 16x^2 + 8x^3 +64x^2 + 128x+16x^2+128x+256 ) (x^2 + 8x+16)$

$\bold{basic \ addition \ of \ integers }$

$\rightarrow \sf (x^4+16x^3+96x^2+256x+256) (x^2 + 8x+16)$

$\bold{remove \ parenthesis}$

$\rightarrow \sf (x^6 + 16x^5 + 96x^4 + 256x^3 + 256x^2 + 8x^6 + 128x^4 + 768x^3 + 2048x^2 + 2048 + 16x^4 + 256x^3 + 1536x^2 + 4096x + 4096)$

$\bold {final \ answer:}$

$\rightarrow \sf x^6+24x^5+240x^4+1280x^3+3840x^2+6144x+4096$

How do i find the square root of a number that is not a perfect square?

nlexa [21]

"Calculate the square root of 10 (√ 10) to 4 decimal places.<span>Find the perfect square number closer to 10. 32 = 9 and 42 = 16, so take 3.Divide 10 by 3. 10÷3 = 3.33 (you can round off the answer)Average 3.33 and 3. ( 3.33 + 3)÷2 = 3.1667."

Simplify without using the absolute value sign<br><br> | x- ( - 18) | if x > - 18

slega [8]

The expression would be > 0.

Subtracting a negative is the same as adding a positive; therefore -18--18 = -18+18 = 0. Since we know that x>-18, 0 is below anything we could get from this.
