Let me try my best to help you out :) ❤️

A) if the area of the square is 81, than that will mean that the length of all the sides are 9. You find the Perimeter by adding up all of the sides. So that will mean you do 9+9+9+9 which equals 36.

B) The diagonal that I got for the square is 12.728. The formula to find the diagonal is d=a sqrt 2.

Hope this helps!

Step-by-step explanation:

write what you know

square- all sides are equal

area of a square

A = L x W

where A = 81

L = sqrt(81)

W = sqrt(81)

perimeter the length around the square

P = sum of all sides

you can find hypotenuse using pythagorean thm

c=sqrt( L^2 + W^2)

Kinda confused on this question.

salantis [7]

6x+5= 9x-4
9=3x
3=x
To find RS you need to substitute x back into the equation
9(3)-4
27-4
23

23 is the answer

Let x1 = 12, y1 = 15, and y2 = 3. Let y vary inversely with x. Find x2.

vladimir1956 [14]

Answer:

x2 = 60

Step-by-step explanation:

If the variables x and y are inversely proportional, the product x * y is a constant.

So using x1 and y1 we can find the value of this constant:

$x1 * y1 = k$

$12 * 15 = k$

$k = 180$

Now, we can use the same constant to find x2:

$x2 * y2 = k$

$x2 * 3 = 180$

$x2 = 180 / 3 = 60$

So the value of x2 is 60.
