Step-by-step explanation:

Here, we want to choose out of the options the one that represents the values of the sides of a triangle

The important thing to note here is like a law that would help us resolve this.

The rule is that the length of the two other sides must add up to be greater than the third side

With this, we shall be shopping for answers;

According to the law, the only answer is B

It is only in B that the sum of the length of two of the sides is greater than the third

The product of three and a squared number is twice the sum of the number and four

Mamont248 [21]

From the text of the task we can write the equation:

$3 x^{2} =2(x+4)\\
\\
3x^2=2x+8\\
\\
3x^2-2x-8=0\\
\\
\Delta=(-2)^2-4.3.(-8)=4+96=100\\
\\
x=\frac{2 \pm\sqrt{100}}{2.3}=\frac{2 \pm10}{6}\\
\\
x_1=\frac{2-10}{6}=-\frac{8}{6}=-\frac{4}{3}\\
\\
x_2=\frac{2+10}{2.3}=\frac{12}{6}=2$

Helen [10]

Answer:

A dilation that creates a smaller image is called a reduction. A dilation stretches or shrinks the original figure. A description of a dilation includes the scale factor (or ratio) and the center of the dilation. The center of dilation is a fixed point in the plane.
