X=-8-3y and x=(23+3y)/4

Since the solution has y=y and x=x we can say:

-8-3y=(23+3y)/4

-32-12y=23+3y

-32-15y=23

-15y=55

y=-11/3, and since x=-8-3y, x=-8+11=3

so the solution is:

(3, -11/3)

Find the first three terms of the sequence with nth term 3n-2​
kykrilka [37]

Answer:

To find out the first three terms of 3n - 2 substitute 1 ,2 and 3 into the equation.

so the three terms a

 3(1)-2=1

3(2)-2=6-2=4

3(3)-2=9-2=7

As you can see the sequence goes up in 1,4 and 7.To find out the 10th term you also substitute 10 into the equation so 3(9)-2=18-2=16

so 16 is the tenth term

Hope this helped!

Answer:

L = 5\sqrt{10}

Step-by-step explanation:

use Pythagorean Theorem:

L² + (5\sqrt{2})² = (10\sqrt{3})²

L² + 25(2) = 100(3)

L² + 50 = 300

L² = 250

L = \sqrt{250} = \sqrt{25} · \sqrt{10} = 5\sqrt{10}

Answer:

  47 -6√10

Step-by-step explanation:

As you know, the area of a square is the square of the side length. It can be helpful here to make use of the form for the square of a binomial.

  (a -b)² = a² - 2ab + b²

  (√2 -3√5)² = (√2)² - 2(√2)(3√5) + (3√5)²

  = 2 - 6√10 + 3²(5)

  = 47 -6√10

__

<em>Check</em>

  √2-3√5 ≈ -5.29399 . . . . . . . . note that a negative value for side length makes no sense, so this isn't about geometry, it's about binomials and radicals

  (√2-3√5)² ≈ 28.02633

  47 -6√10 ≈ 28.02633
