Answer:

No real solutions.

B is correct

Step-by-step explanation:

Given: 3x^2+x+10=0

We are given a quadratic equation and need to solve for x.

Quadratic formula: ax^2+bx+c=0

x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

For our equation, a=3, b=1 and c=10

Substitute the value of a, b and c into formula

x=\dfrac{-1\pm\sqrt{1^2-4\cdot 3\cdot 10}}{2\cdot 3}

x=\dfrac{-1\pm\sqrt{-119}}{6}

Here, Roots are imaginary because number inside the square root is negative.

Hence, No real solutions.

First we find half the coefficient of x:

\begin{gathered} \frac{1}{2}\text{ of B}=\frac{B}{2} \\  \end{gathered}

<h3>1.</h3>

The picture shows 5 groups of 3 bars. Each bar represents 1/10. We take the picture to mean that ...

... (15/10) / 5 = 3/10

In decimal:

... 1.5 / 5 = 0.3

<h3>2.</h3>

The picture shows 3 groups of 2 bars. Each bar represents 1/10. We take the picture to mean that ...

... (6/10) / 3 = 2/10

In decimal:

... 0.6 / 3 = 0.2

<h3>3.</h3>

The picture shows 4 groups, each consisting of 1 large square, 1 bar, and 4 small squares. We take the picture to mean that ...

... (4 + 4/10 + 16/100) / 4 = 1 + 1/10 + 4/100

In decimal:

... 4.56 / 4 = 1.14

Please note that 16/100 is equivalent to 1/10 + 6/100. In order to do the division, one of the 1/10 bars needed to be changed into 10 small squares, 10/100.

<h3>4.</h3>

The picture shows 3 groups, each consisting of 1 large square, 3 bars, and 2 small squares. We take the picture to mean that ...

... (3 + 9/10 +6/100) / 3 = 1 +3/10 + 2/100

In decimal:

... 3.96 / 3 = 1.32

Answer gets brainliest PLS HELP!!

Based on the number of days that the health inspector and the fire inspector visits, the table for their next 4 visits is:

Number of visits        Health Inspector visits           Fire inspector visits

          1                                             7                                          12

          2                                            14                                        24

          3                                             21                                        36

           4                                            28                                       48

The number of days till both inspectors visit on the same day is 84 days.

<h3>What day will both inspectors visit?</h3><h3 />

The model that would be best to use and solve the problem of the number of days till both inspectors visit is the Lowest Common Multiple.

This shows the number of days till both inspectors would visit based on their visiting interval.

The lowest common multiple of 7 and 12 is 84 which means that the health and fire inspectors would visit after 84 days on the same day.
