The sum of squares of two consecutive odd numbers is 514 find the numbers

amid [387]

Correct Question : The sum of squares of two consecutive positive odd numbers is 514. Find the numbers.

$\rule{130}1$

Solution :

Let the two consecutive positive odd numbers be x and (x + 2)

$\rule{130}1$

☯ $\underline{\boldsymbol{According\: to \:the\: Question\:now :}}$

$:\implies\sf x^2 + (x + 2)^{2} = 514 \\\\\\:\implies\sf x^2 + x^2 + 4x + 4 = 514\\\\\\:\implies\sf 2x^2 + 4x + 4 = 514 \\\\\\:\implies\sf 2x^2 + 4x = 514 - 4\\\\\\:\implies\sf 2x^2 + 4x = 510 \\\\\\:\implies\sf 2x^2 + 4x - 510 = 0\\\\\\:\implies\sf x^2 + 2x - 255 = 0 \:\:\:\:\:\Bigg\lgroup \bf{Dividing\:by\:2}\Bigg\rgroup\\\\\\:\implies\sf x^2 + 17x - 15x - 255 = 0\\\\\\:\implies\sf x(x + 17) - 15(x + 17) = 0\\\\\\:\implies\sf (x + 17) (x - 15)\\\\\\:\implies\sf x = - 17\:or\:x = 15\\\\\\:\implies\underline{\boxed {\sf x = 15}}\:\:\:\:\:\Bigg\lgroup \bf{Positive\:odd\: number}\Bigg\rgroup$

When,

$\bullet\: \textsf {x = } \textbf {15}$

$\bullet\: \sf x + 2 = 15 + 2 =\textbf{ 17}$

$\therefore\:\underline{\textsf{The required positive integer is \textbf{15 and 17}}}.$

Flura [38]

Answer:

$125y^5$

Step-by-step explanation:

$\mathrm{Factor}\:\left(5y\right)^{-2}:\quad 5^{-2}y^{-2}$

$\mathrm{Cancel\:}\frac{5y^3}{5^{-2}y^{-2}}:\quad 5^3y^5$ $=5^3y^5$

$5^3=125$

Write a compound inequality for the following graph. -3 -2 2 3 6 7 8 0 -2 < 1 >5 O–25 0-2

Mademuasel [1]

First we see there are two extremes, two limits

-2 and 5

x is between them

BUT theres a difference , the point at left is black

the point at right is white rounded

this means x is equal or less than -2

and x is ONLY less than 5 , not equal

so this means the answer is the d option

QUICK ILL GIVE YOU 30 PTS IF YOU CAN SOLVE IT WITH A CLEAR EXPLANATION

Virty [35]

Answer:

X=27

Step-by-step explanation:

90+36=126

180-126=54

54/2=27

The line is strait therefore it is 180 degrees and the right angle is 90 plus the 36 angle equals 126. Then you take that away from 180 to find how much the other angle is. After you find that it is 54 you divide it by 2 because it is 2x.
