Begin by factoring 2 out of 2x^2 - 2x - 12 equals 0:

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0. 2 is never zero, but x-3 and x+2 can each be set = to 0:

This results in x = 3 and x = -2. The equation is true for these two x-values.

The solution to the problem expressed 2358.

<h3>What is the meaning of significant figure?</h3>

Significant figure It is defined as the minimum number of digit us needed to express a number in scientific notation.

Therefore we get,

$15.11+(142\times16.5)$

First we have to multiply the given digits as per rule.

$=15.11+2343$

Now we will add both the digits, we get

$=2358.11$

As per given expression, we conclude that the number of significant figure is 4.

So, the answer will be, 2358.

Therefore, the correct option is, 2358.

$6\frac{2}{3}\implies 6+\frac{2}{3}\implies \stackrel{\textit{three times that much}}{3\left( 6+\frac{2}{3} \right)\implies} (3\cdot 6)+3\left( \frac{2}{3} \right)\implies 18+2\implies \underset{meters}{20}$
