Number two please <br> ASAP

The solutions for $-5 +2x^{2} = -6x$ is option 3. $x= \frac{-6 \pm \sqrt{36-4 (2)(-5)}}{4} .$

Step-by-step explanation:

Step 1:

First, we must bring the equation to the form of $ax^{2} +bx +c =0.$

So $-5 +2x^{2} = -6x$ becomes $2x^{2} +6x-5=0.$

The value of a is the coefficient of the $x^{2}$ term, the value of b is the coefficient of x term and c is the coefficient of the constant term.

Comparing the above equation to $ax^{2} +bx +c =0,$ we get $a = 2, b = 6,$ and $c=-5.$

We have the formula $x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}.$

Step 2:

By substituting the known values, we get

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a} =\frac{-6 \pm \sqrt{6^{2}-4 (2)(-5)}}{2 (2)}.$

$\frac{-6 \pm \sqrt{6^{2}-4 (2)(-5)}}{2 (2)} = \frac{-6 \pm \sqrt{36-4 (2)(-5)}}{4} .$

This is the third option.

Philly and Boston were working on a project in carpentry class. They needed to cut 5 lengths of 2 3/4 feet from a board. How lon

Anna71 [15]

The board must be at least as big as the project's length needed,
so, it needs to be at least $\left( 2\frac{3}{4} \right)+\left( 2\frac{3}{4} \right)+\left( 2\frac{3}{4} \right)+\left( 2\frac{3}{4} \right)+\left( 2\frac{3}{4} \right)
\\ \quad \\
or
\\ \quad \\
5\cdot \left( 2\frac{3}{4} \right)\implies \boxed{?}$
