Answer:

  (x +5)^2 = -2

Step-by-step explanation:

We can subtract the constant to get ...

  x^2 +10x = -27

Then add the square of half the x-coefficient:

  x^2 +10x +5^2 = -27 +5^2

  (x +5)^2 = -2 . . . . . . write as a square

20/12=15/x find x plz help
Ganezh [65]

Answer:

x = 9

Step-by-step explanation:

To find x, we first have to solve the equation given in the question:

\frac{20}{12} = \frac{15}{x}

20x = 15 \cdot 12

x = \frac{180}{20}

x = 9

Therefore, x = 9.

Hope this helped!

STALIN [3.7K]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the options to select the required condition from were not listed. So, I will answer on general terms

From the question, we understand that the cube has an open-top and the surface ares is 256 in^2

Let L represents the edge length, the surface area (S) is:

S = 5L^2

Substitute 256 for S

256 = 5L^2

Divide both sides by 5

51.2 = L^2

Take square roots of both sides:

\sqrt{51.2} = L

7.155= L

L=7.16in ---- approximated

The volume of the cube is:

Volume = L^3

Volume = \sqrt{51.2}^3

Volume = 366.3573

Volume = 366.36in^3

<em>So, the edge length of the cube is 7.16 inches and the volume is 366.36 cubic inches</em>
