Find x using the picture below.

Katen [24]

Answer:

x ≈ 14.5

Step-by-step explanation:

A = x²√(25+10√5)/4

A = 1.72a²

x² = A/1.72

= 363.27/1.72

≈ 211

x = √211

≈ 14.5

Find the value of x in the triangle

miss Akunina [59]

Answer: $\sqrt{52}$

Step-by-step explanation:

a^2 +b^2 = c^2

4^2 = 16

6^2 = 36

Select two polynomials that have a sum of 16n^3+13n^2+7n-10 A. 8n^3 - 5n +11n^2 - 5 B. 7n^2 + 8n - n^3 + 2 C. 15n^2 - 10n + 3n^3

andreyandreev [35.5K]

Answer:

Step-by-step explanation:

We have the polynomial

$16n^3+13n^2+7n-10$ ( 1 )

To solve this problem we have to take into account that only we can sum term with the same order in the variable. We have the polynomials

$8n_{3}-5n+11n^{2}-5\\7n^2 + 8n - n^3 + 2\\15n^2 - 10n + 3n^3 - 4\\2n^2 + 12n - 5 + 8n^3$

we can note (by summing term by term) that only the sum of the first and the fourth equation correspond to the given polynomial ( 1 ) of the problem. If we organize these polynomials (that is, write the equation down in a form where higher order appears first ) we have

$8n^3 +11n^2 - 5n - 5\\ 8n^3+2n^2 + 12n - 5\\$

and if we sum we obtain

$16n^3+13n^2+7n-10$

that is what we was looking for

I hope this is useful for you

PLEASE HELP QUICK!!!!! WILL GIVE BRAINIEST!!!!!

lisabon 2012 [21]

Answer:

-2

Step-by-step explanation:

its -2 cuz to find the slope the equation is the second y - the first y over the second x - the first x so -5 - 5 is 10 over 3 - -2 is 5 so it would be -10/5 which simplifies to -2

Which of the following numerical expressions results in a negative number? (-21) - (-22) (-13) - (-8) 15 - (-7) - 19 (-37) - (-4

Viktor [21]

Answer:

-13 + 8 = -5 (negative number)

Step-by-step explanation:

(-21) - (-22)

-21 + 22 = 1 (positive number)

(-13) - (-8)

-13 + 8 = -5 (negative number)

15 - (-7) - 19

15 + 7 - 9

22 - 9 = 13 (positive number)

(-37) - (-45)

-37 + 45 = 8 (positive number)

Hope this helps!
