Answer:

51.84 cm

Step-by-step explanation:

Solution,

We have,

Area of the square= L²

According to question,

168 cm²= L²

√168 cm²= L²

√(12.96 cm)² = L

12.96 cm= L

Now,

We got,

Length of the square= 12.96 cm

By using the formula of perimeter of square,

We have,

Perimeter of square= 4L

=4×12.96 cm

=51.84 cm

Hence, the perimeter of square is 51.84 cm.

Find the zero places of the quadratic function: y= x^2 + 5x + 6
andre [41]

The required zero places of the given equation  y= x² + 5x + 6 is x = -2 and x = -3.

Given that,
An equation   y= x² + 5x + 6,
To determine the Zeros of the equation given above.

<h3>What is the equation?</h3>

The equation is the relationship between variables and is represented as y =ax + b is an example of a polynomial equation.

Here, given equation is, y= x² + 5x + 6
Now, let y = 0
x² + 5x + 6 = 0
x² + 2x + 3x + 6 = 0
x(x + 2) + 3 (x + 2) = 0
(x + 2) * (x + 3) = 0
x + 2 = 0    ;   x + 3 = 0
x = -2  and x = -3

Thus, the required zero places of the given equation  y= x² + 5x + 6 is x = -2 and x = -3.

What is the value of X?<br><br> 80 cm<br> 20 cm<br> 12 cm<br> 10 cm
dangina [55]

Answer:

x=12cm

Step-by-step explanation:

Triangle DEF is similar to triangle HGF.

Therefore the corresponding sides are proportional.

We can write the following equations for the corresponding sides.

\frac{DF}{HF}=\frac{EF}{GF}


This implies that,

\frac{16+40}{40}=\frac{x+30}{30}


This gives us,


\frac{7}{5}=\frac{x+30}{30}


We cross multiply to get,

7\times 30=5(x+30)


We divide through by 5 to get,


7\times 6=(x+30)

We multiply to get,

\Rightarrow 42=x+30

Grouping like terms gives,

\Rightarrow 42-30=x

We simplify to obtain,

\therefore x=12cm


The correct answer is C
