1 answer:

8 0

We Know, perimeter of square = 4a
Area of square = a²

Now, A.T.Q,
8*4a = a²
32a = a²
a²/a = 32
a = 32

So, side should be 32

Hope this helps!

Which expression is equivalent to 3 sqrt 27x^18

shusha [124]

Assuming your original expression was 3√(27x¹⁸), the answer is 9x⁹√(3).

We split up the radicand into perfect squares. Once we do, we take out the things that were squared:
$3\sqrt{27x^{18}} = 3\sqrt{3\times3\times3x^2x^2x^2x^2x^2x^2x^2x^2x^2x^2} = 3*3*xxxxxxxxx\sqrt{3}
$
$=9x^9\sqrt{3}$

What value of z makes the equation z+6÷13=4 true?

netineya [11]

Answer:

z = 46/13

Step-by-step explanation:

Step 1: Write equation

z + 6 ÷ 13 = 4

Step 2: Solve for <em>z</em>

Rewrite: z + 6/13 = 4
Subtract 6/13 on both sides; z = 46/13

Step 3: Check

<em>Plug in z to verify it's a solution.</em>

46/13 + 6/13 = 4

52/13 = 4

4 = 4
