Answer:

  Molly

Step-by-step explanation:

Brady did not properly create a square.

The square of a binomial is ...

  (a -b)² = a² -2ab +b²

Where a²=x² and -2ab = -4x, you find b=2. The constant term in the square is 2²=4. Brady shows it as -4, which is incorrect.

Molly's work is correct.

Which line has a slope of 5/8 and goes through the point (2,-3)?
QveST [7]

\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{-3})\qquad \qquad \qquad 
slope =  m\implies \cfrac{5}{8}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-3)=\cfrac{5}{8}(x-2)
\\\\\\
y+3=\cfrac{5}{8}x-\cfrac{5}{4}\implies y=\cfrac{5}{8}x-\cfrac{5}{4}-3\implies y=\cfrac{5}{8}x-\cfrac{17}{4}


\bf \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{8}}{8y=5x-34}\implies -5x+8y=-34 \\\\\\ \stackrel{\textit{multiplying both sides by -1}}{5x-8y=34}\impliedby standard~form


bear in mind that in a standard form of a linear equation


the variables are both on the left side, "x" before the "y" usually.


"x" cannot have a negative coefficient.


all coefficients and constants must be integers.

which of the three sets could not be the lengths of the sides of a triangle {6,10,12} {5,7,10} {4,4,9} {2,3,3}
Phoenix [80]

So for this, we will be applying the Triangle Inequality Theorem, which states that the sum of 2 sides must be greater than the third side for it to be a triangle. If any inequality turns out to be false, then the set cannot be a triangle.

A+B>C\\A+C>B\\B+C>A

<h2>First Option: {6, 10, 12}</h2>

Let A = 6, B = 10, and C = 12:

6+10>12\\16>12\ \textsf{true}\\\\6+12>10\\18>10\ \textsf{true}\\\\12+10>6\\22>6\ \textsf{true}

<h2>Second Option: {5, 7, 10}</h2>

Let A = 5, B = 7, and C = 10

5+7>10\\12>10\ \textsf{true}\\\\5+10>7\\15>7\ \textsf{true}\\\\10+7>5\\17>5\ \textsf{true}

<h2>Third Option: {4, 4, 9}</h2>

Let A = 4, B = 4, and C = 9

4+4>9\\8>9\ \textsf{false}\\\\4+9>4\\13>4\ \textsf{true}\\\\4+9>4\\13>4\ \textsf{true}

<h2>Fourth Option: {2, 3, 3}</h2>

Let A = 2, B = 3, and C = 3

2+3>3\\5>3\ \textsf{true}\\\\2+3>3\\5>3\ \textsf{true}\\\\3+3>2\\6>2\ \textsf{true}

<h2>Conclusion:</h2>

Since the third option had an inequality that was false, <u>the third option cannot be a triangle.</u>
